From fbb84269ea8a856d72f6d8b4cef4c720d14a6696 Mon Sep 17 00:00:00 2001 From: hasan-ismail Date: Fri, 31 Jul 2026 21:03:56 -0400 Subject: [PATCH 01/16] docs(audit): full security and code-health audit report 23 findings (0 critical, 3 high, 7 medium, 9 low, 4 info) against main @ 4f4a7f0. Compose findings adjudicated against real Docker Compose v5.3.1; prayer-time findings verified numerically. Autonomous push to main was disabled by pre-flight: catalog.json on main IS the production artifact the platform fetches, and pushing scripts/** additionally triggers an unattended rebuild that re-publishes it with a branch-protection-bypassing PAT.

Excludes the five external app +repositories the registry points at (audited in their own repos) and the OpenMasjidOS platform. + +--- + +## Executive summary + +**Posture: good, with two exploitable gaps in the exact control this repo exists to provide.** + +This is a small, unusually well-documented repository, and its security-relevant intent is explicit — `CLAUDE.md` +§10 names the compose validator as "the catalog's safety gate" and states the invariant *"passes the catalog build == +safe to install."* The hygiene is genuinely strong: **zero secrets in 475 commits** across 18 credential patterns, +zero dependency vulnerabilities, one dependency, an SPDX header on every file, and a compose validator that already +catches every directive its own documentation lists. Most of what follows is *"the stated control has a hole,"* not +*"there is no control."* + +**The single most important issue is APPS-001.** A registry entry's `path:` field is interpolated into a +`raw.githubusercontent.com` URL without any traversal check, so `path: ../../../../attacker/evil/main` makes an entry +that reads — in the file, in code review, and in the build log — as +`OpenMasjid-Solutions/TrustedApp @ a32816bf…` actually fetch its manifest and compose from +`attacker/evil@main`. The 40-character `commit:` SHA, which `registry.yaml` and `CLAUDE.md` both name as *the only +immutable pin* and the sole integrity control for the unattended nightly rebuild, is silently bypassed while still +appearing to be honoured. Because `build-catalog.yml` auto-commits and pushes the regenerated `catalog.json` using a +PAT specifically chosen to bypass branch protection, the resulting compose reaches every OpenMasjidOS App Store with +no further human step. Verified end to end (Probe 7). + +Close behind, **APPS-002**: the validator has a careful `checkExternalVolumes` rule preventing an app from attaching +to another app's data volume, but **no equivalent rule for networks**. `networks: {omos_internal: {external: true}}` +is valid Docker Compose (confirmed against Docker Compose v5.3.1) and passes the validator with zero errors *and zero +warnings*, letting a listed app place itself directly on a pre-existing Docker network. The asymmetry with the volume +check is what makes this an oversight rather than a decision. + +**APPS-003** is the finding to read if you care about harm rather than compromise. The reference prayer-time engine +clamps the hour-angle equation into `[-1, 1]` when the sun never reaches the Fajr/Isha depression angle, converting +*"this is not computable"* into a specific, confident, wrong number. London on 21 June returns **Fajr 01:02 and Isha +01:02** — the same instant, which is impossible. Berlin and Stockholm likewise. This is not currently shipped (no +example app is in `registry.yaml`), which is the only reason it is High and not Critical — but `CLAUDE.md` §1 and +`docs/BUILDING_AN_APP.md` both direct every new app author to copy this file as their starting point. + +One documentation claim is false in a way that matters: `docs/BUILDING_AN_APP.md:573` promises discovery labels are +*"Rejected at build AND at install."* The validator does not look at labels at all (APPS-004). + +### Ship decision + +**Autonomous push to `main` was disabled by pre-flight rule 2.** `catalog.json` on `main` *is* the production +artifact — the platform fetches the raw file directly, with no build or deploy gate — and pushing paths under +`scripts/**` additionally triggers a workflow that regenerates and re-publishes it unattended.

There is no server, no database, no HTTP listener, no authentication system, +and no user accounts in this repository — a large share of the standard audit surface is genuinely absent here, and +is marked as such below rather than padded. + +**Entry points** (complete list): + +| # | Entry point | Trust | Notes | +|---|---|---|---| +| 1 | `registry.yaml` via PR | semi-trusted | Human-merged; CLA-gated.

The platform holds zero masjid/prayer data." This repository stores no PII, no payment data, no +credentials. The nearest thing is contributor GitHub usernames in CLA signatures, which live on the unprotected +`cla-signatures` branch and are already-public identifiers (APPS-022).

The `replace()` strips leading +and trailing slashes only — **`..` survives**. `resolveRefToSha()` at line 141 does `encodeURIComponent(ref)`; this +function encodes nothing, so the two are inconsistent about the same input. + +**Attack path.** Open a registry PR whose entry looks maximally trustworthy — a first-party `repo:`, a real 40-hex +`commit:` — and add a `path:`: + +```yaml +- id: display + repo: OpenMasjid-Solutions/OpenMasjidDisplay + commit: a32816bf5e3e3576b4a0bcfb400713b12383e98f + path: ../../../../attacker/evil/main +``` + +Verified (Probe 7): + +``` +constructed : https://raw.githubusercontent.com/OpenMasjid-Solutions/TrustedApp/aaaa…aaaa/../../../../attacker/evil/main/manifest.yaml +resolves to : https://raw.githubusercontent.com/attacker/evil/main/manifest.yaml +``` + +**Impact.** Every control the repo documents as protecting the unattended rebuild is defeated *while still appearing +to be in force*: `registry.yaml`'s own comment calls a `commit:` SHA "the ONLY immutable pin"; the build prints +`✓ display ← OpenMasjid-Solutions/OpenMasjidDisplay@a32816bf…`, naming the innocent repo; and `immutable` is `true`, +so no ⚠ warning is emitted. The attacker's ref is `main` — mutable — so content can be changed *after* the PR is +merged and reviewed, and the nightly job republishes it. `CATALOG_PUSH_TOKEN` bypasses branch protection, so there is +no second human gate before it is live to every App Store. Not remotely exploitable without a merged PR, which is why +this is High and not Critical. + +**Fix.** Validate all three fields structurally before any URL is built: `repo` must match +`^[A-Za-z0-9._-]+/[A-Za-z0-9._-]+$`, `ref` must match `^[A-Za-z0-9._/-]+$` and contain no `..`, and `path` must be a +relative POSIX subpath with no `..` segment. `encodeURI` the assembled base. Each field is also rejected if it +contains a control character or `%`. Regression-tested in `scripts/__tests__/build-catalog.test.mjs`. + +--- + +### APPS-002 — Compose validator has no external/renamed network check · **High** · Confirmed + +**Where:** [`scripts/validate-compose.mjs:195-225`](../../scripts/validate-compose.mjs#L195-L225) + +The validator contains a deliberate, well-commented rule stopping an app from attaching to storage it does not own: + +```js +// `external: true` uses the volume name verbatim and `name:` overrides the +// project-scoped name, so either can attach to ANOTHER app's data … +// Every OpenMasjid app's data lives in an `omos-*` volume. +``` + +There is **no counterpart for `networks:`.** Confirmed (Probe 4 + Docker Compose v5.3.1): + +```yaml +services: + a: + image: nginx:alpine + networks: [omos_internal] +networks: + omos_internal: + external: true +``` +``` +docker compose config -> VALID (name: omos_internal ; external: true) +validateCompose(...) -> { "errors": [], "warnings": [] } <-- passes clean +``` + +The `name:`-override variant (`networks: {default: {name: omos_core_default, external: true}}`) is likewise valid and +likewise passes clean. `classifyVolumeSource` never sees a network, so the existing machinery cannot catch it. + +**Impact.** A listed app can place its container on a pre-existing Docker network instead of its own project network, +reaching containers that the per-app project boundary is supposed to separate — the platform core's internal API and +other installed apps' unauthenticated internal ports. Combined with the Fabric design, where an app's authority is +supposed to be bounded by a per-app secret, this is a way to bypass that boundary at the network layer. Every listed +app is a candidate attacker; no PR merge is needed beyond the app's own updates. + +**Confidence.** The validator gap and the compose validity are **Confirmed**. What is specifically reachable on an +`omos_*` network is **Likely** and needs platform-side verification — I cannot see the OpenMasjidOS repo from here, +so the exact blast radius is unverified. The fix is correct regardless: *a listed app must own its network*, exactly +as it must own its storage. + +**Fix.** New `checkNetworks()` mirroring `checkExternalVolumes` — reject any top-level network that is `external` +or carries an explicit `name:`, with a distinct message when the target matches `^omos[-_]`; also reject a +`driver: host`/`none` network and any `network_mode` reference to a network the file does not define. Per Tier 3, the +matching change in the platform's `apps/compose-validate.ts` is **not** made here and is recorded in +`ACTION_REQUIRED.md`. + +--- + +### APPS-003 — High-latitude clamp fabricates wrong Fajr and Isha · **High** · Confirmed + +**Where:** [`examples/prayer-times-display/src/js/prayer.js:95-118`](../../examples/prayer-times-display/src/js/prayer.js#L95-L118) + +```js +const depressionOffset = (angle) => { + const x = (-dsin(angle) - dsin(lat) * dsin(decl)) / (dcos(lat) * dcos(decl)); + return darccos(clamp(x, -1, 1)) / 15; // <-- clamp +}; +``` + +When the sun never descends to the Fajr (18°) or Isha (17°) depression angle — persistent twilight, which is the norm +above roughly 48°N from late May to late July — `|x| > 1` and the hour angle has **no solution**. `clamp()` does not +signal that; it silently substitutes `arccos(-1) = 180°`, i.e. an offset of exactly 12 hours, and the function returns +a plausible-looking clock time. + +**Verified** (Probe 1, MWL / Standard Asr): + +``` +London 51.51N Jun21 BST fajr=01:02 sunrise=04:43 dhuhr=13:02 asr=17:25 maghrib=21:21 isha=01:02 <-- FAJR == ISHA +Berlin 52.52N Jun21 CEST fajr=01:08 sunrise=04:43 dhuhr=13:08 asr=17:33 maghrib=21:33 isha=01:08 <-- FAJR == ISHA +Stockholm 59.33N Jun21 fajr=00:50 sunrise=03:31 dhuhr=12:50 asr=17:30 maghrib=22:08 isha=00:50 <-- FAJR == ISHA +Toronto 43.65N Jun21 EDT fajr=03:13 … isha=23:14 (correct) +Cairo 30.04N Jun21 EET fajr=03:18 … isha=20:30 (correct) +``` + +`Fajr == Isha` is not merely inaccurate, it is impossible — and the display renders it with no indication of doubt. +London's Fajr by the usual conventions is around 02:40 BST, so the number shown is nearly two hours early: a +congregation praying Fajr before its time, which is an invalid prayer. `formatClockTime` normalises `isha = dhuhr + +12h = 25.05` into `01:02`, so both errors present as ordinary times. + +Two compounding gaps: there is **no high-latitude adjustment method** at all (the standard options are Middle of the +Night, One-Seventh of the Night, and Angle-Based), and none is configurable, contrary to `CLAUDE.md` §11 *"Make +masjid-specific values configurable, never hard-coded."* + +**Severity rationale.** Not Critical, because nothing here is shipped: no example is in `registry.yaml` and both +candidate entries are commented out. It is High because `CLAUDE.md` §1 and §4A and `docs/BUILDING_AN_APP.md` all +present this file as the starting point every app author copies, so the defect is positioned to propagate into apps +that *will* ship. It becomes Critical the day one does. + +**Fix.** `depressionOffset` now returns `NaN` when no solution exists instead of clamping. A `highLatRule` setting +(`MiddleOfNight` default, `OneSeventh`, `AngleBased`, `None`) supplies the standard fallbacks, computed from the true +night length between sunset and sunrise. With `None`, the value stays `NaN` and the UI renders "—" plus a one-line +explanation rather than a fabricated time. `clamp` is retained only for genuine floating-point overshoot +(`|x| < 1 + 1e-9`).

Demonstrated locally: a plain `npm install` modified `package-lock.json` on a clean tree. + +**Impact.** The job this runs in has `contents: write`, holds a branch-protection-bypassing PAT, and auto-commits +`catalog.json`. A malicious `yaml` release inside `^2.5.0` would execute in that job, unattended, at 06:17 UTC, with +publish rights over the file every masjid installs from.

It is Medium because `examples/` has exactly one job — being the thing app authors +copy (`CLAUDE.md` §1, §4A; `docs/BUILDING_AN_APP.md`) — and it cannot do that job. An author following the documented +path starts from a broken app and has no icon, which is a required field. + +**Fix.** All eight files restored byte-for-byte from `cabcbae^` (each reviewed before restoration: no inline handlers, +no remote resources, data-URI favicon, no `innerHTML` seeding). RTL and performance changes are separate commits so +the restore stays a clean, auditable revert of an accidental deletion. + +--- + +### APPS-009 — RTL never enabled although `ar`/`ur` are offered · **Medium** · Confirmed + +**Where:** [`examples/prayer-times-display/src/js/app.js:187-189`](../../examples/prayer-times-display/src/js/app.js#L187-L189) + +```js +document.documentElement.dataset.orientation = config.orientation; +document.documentElement.lang = config.language; // no dir +``` + +Both manifests offer `LANGUAGE: [en, ar, ur]`. Arabic and Urdu are right-to-left; `lang` is set, `dir` never is, and +the recovered stylesheets contain no `[dir="rtl"]` rules (one lone `inset-inline-start`; the other apparent matches +were `flex-direction`). A masjid selecting Arabic gets Arabic text in a left-to-right layout. + +This contradicts the repo's own contract twice over — `docs/DESIGN.md:50` *"**RTL first-class** — Arabic/Urdu must +render correctly (use logical CSS properties everywhere)"* and the `docs/DESIGN.md:432` release checklist *"Works +**LTR and RTL**"*. `docs/DESIGN.md:36` even supplies the exact intended line, which removes any ambiguity about the +intended rule: + +```js +document.documentElement.dir = ['ar', 'ur', 'fa'].includes(prefs.lang) ? 'rtl' : 'ltr'; +``` + +**Fix.** That line, verbatim, in both example apps, plus logical properties and `[dir="rtl"]` mirroring for the +directional rules in both stylesheets, and an Arabic/Urdu Naskh font fallback per `docs/DESIGN.md:292`. + +--- + +### APPS-010 — Hijri date does not roll over at maghrib · **Medium** · Confirmed + +**Where:** [`examples/prayer-times-display/src/js/app.js:64-74`](../../examples/prayer-times-display/src/js/app.js#L64-L74) + +```js +.format(new Date(Date.UTC(parts.year, parts.month - 1, parts.day, 12))); +``` + +The Hijri date is derived from noon on the civil date, so it changes at civil midnight. The Islamic day begins at +**maghrib**. Between sunset and midnight the display therefore shows a date one day behind what the masjid is +announcing — every single evening, including on the nights that matter most (27 Ramaḍān, ʿEid eve, ʿArafah). + +The calendar choice itself is right: `islamic-umalqura` is the Umm al-Qurā civil calendar, consistent with the +`Makkah` method already offered. Only the rollover boundary is wrong. + +**Fix.** Advance the Hijri date by one day once the current time is at or past the computed maghrib. This is +behaviour-changing and therefore flagged as Tier 2 in `REMEDIATION.md`. It is not ambiguous — maghrib rollover is the +convention every masjid uses — but it is the one change here that alters what a screen already displays, so it is +listed first for you to sanity-check. + +--- + +### APPS-011 — `cgroup_parent` and `sysctls` unchecked · **Low** · Confirmed + +**Where:** [`scripts/validate-compose.mjs:168-186`](../../scripts/validate-compose.mjs#L168-L186) + +The validator rejects `cgroup: host` but not `cgroup_parent:`. Both confirmed valid Docker Compose and passing clean: + +``` +VALID cgroup_parent -> cgroup_parent: /docker/evil [*** PASSES CLEAN ***] +VALID sysctls -> net.ipv4.ip_forward: "1" [*** PASSES CLEAN ***] +``` + +`cgroup_parent` lets a container be placed outside the cgroup slice the platform assigns it, escaping memory and CPU +limits — which matters on the Raspberry Pi class of hardware this platform targets. `sysctls` is bounded: Docker only +permits namespaced sysctls without `--privileged`, so the reachable effect is confined to the container's own network +namespace. Low for both, on real impact. + +**Fix.** `cgroup_parent` is an error (no masjid app needs it; verified unused by all five live apps). `sysctls` is a +warning, not an error — the impact does not justify breaking a legitimate app that tunes its own namespace. + +--- + +### APPS-012 — Scalar-shaped `cap_add`/`security_opt`/`group_add` skip checks · **Low** · Confirmed not exploitable + +**Where:** [`scripts/validate-compose.mjs:176-184`](../../scripts/validate-compose.mjs#L176-L184) + +Three checks are gated on `Array.isArray(...)`, so a scalar value skips them entirely, while the neighbouring +`devices` and `volumes_from` checks correctly handle both shapes. The raw-regex net that would catch these runs +**only when YAML parsing fails**, so a well-formed document slips through: + +``` +[*** PASSES CLEAN ***] cap_add scalar (cap_add: SYS_ADMIN) +[REJECTED] cap_add flow list (control — cap_add: [SYS_ADMIN]) +[*** PASSES CLEAN ***] security_opt scalar +[*** PASSES CLEAN ***] group_add scalar docker +``` + +**Not exploitable, and I want to be precise about that.** Docker Compose v5.3.1 rejects all three shapes: + +``` +INVALID cap_add_scalar -> services.a.cap_add must be a array +INVALID secopt_scalar -> services.a.security_opt must be a array +INVALID groupadd_scalar -> services.a.group_add must be a array +``` + +So such a compose fails at install regardless, and no privilege is actually gained. This is a robustness and +lockstep-hygiene defect, not a bypass — it is Low, and my first read of it as a bypass was wrong until Docker +adjudicated it. + +It is still worth fixing: `CLAUDE.md` §10 makes lockstep with the platform's independent validator a stated +invariant, that validator may normalise shapes differently, and normalising scalar→array can only add rejections for +shapes no valid app uses. + +**Fix.** A `toList()` helper normalises all three before checking. Verified all five live apps use list form. + +--- + +### APPS-013 — No lat/lng range validation · **Low** · Confirmed + +**Where:** [`examples/…/src/js/app.js:16-17`](../../examples/prayer-times-display/src/js/app.js#L16-L17), guard at `:191` + +The existing `Number.isFinite` guard correctly catches blank and non-numeric input and shows a friendly setup screen — +that part is right. What is missing is a **range** check, and `parseFloat` is lenient: + +``` +lat=999 lng=999 -> { fajr: '13:47', sunrise: '17:25', dhuhr: '17:25', asr: '17:25', maghrib: '17:25', isha: '20:28' } +``` + +A transposed or mistyped coordinate yields confident nonsense — sunrise, dhuhr, asr and maghrib all identical — +rather than an error. `parseFloat('12abc')` also silently returns `12`. + +**Fix.** Require latitude in [-90, 90], longitude in [-180, 180], and reject strings with trailing garbage +(`Number()` on a trimmed string, not `parseFloat`). Failures route to the existing setup screen with a specific +message. + +--- + +### APPS-014 — Manifest fields copied into the catalog unvalidated · **Low** · Confirmed + +**Where:** [`scripts/build-catalog.mjs:257-301`](../../scripts/build-catalog.mjs#L257-L301) + +`name`, `tagline`, `description`, `settings`, `ports` and `icon`/`screenshots` are copied from an untrusted remote +manifest into `catalog.json` with no type check, no length limit and no structural validation. `name` is only tested +for truthiness, then `apps.sort()` calls `a.name.localeCompare(b.name)` — a numeric or object `name` throws and +breaks the build. Wrong types silently violate the platform contract in `CLAUDE.md` §2.3 (which specifies +`settings: Array`, `ports: [{container: number}]`). `settings[].key` is not validated as an env-var name, and +`settings[].default` is not checked for newlines even though `CLAUDE.md` §7 requires single-line values because the +platform writes them to `.env` as `KEY=VALUE` — a newline in a default is an `.env` line injection. + +Currently harmless: no live app defines `settings`, no description contains an HTML tag or `javascript:` URI, and +descriptions run 1,135–1,710 characters. + +**Impact.** Reachable only via a listed app's manifest, and the worst confirmed local outcome is a failed build. +`description` is rendered as Markdown on the platform's detail page, so whether hostile Markdown becomes XSS depends +on the platform's renderer — **that is cross-repo and unverified from here.** Per Tier 3 I implement the safe half +(validate and reject at the catalog boundary) and record the platform-side question in `ACTION_REQUIRED.md`. + +**Fix.** Type and length validation for every field copied into an entry: strings must be strings (length-capped: +`name` 120, `tagline` 200, `description` 16 KiB), `settings` must be an array of objects with an +`^[A-Za-z_][A-Za-z0-9_]*$` key, a known `type`, `options` present for `select`, and no control characters or newlines +in `default`; `ports[].container` must be an integer in 1–65535; `icon`/`screenshots` must be relative subpaths with +no `..` or scheme. Caps are set well above the largest live value so nothing currently listed is affected — verified +by rebuilding. + +--- + +### APPS-015 — `.gitignore` gaps; no `.dockerignore` in the templates · **Low** · Confirmed + +[`.gitignore`](../../.gitignore) covers `.env` but not `.env.*` (`.env.local`, `.env.production`), and no key or +certificate material (`*.pem`, `*.key`, `*.p12`, `id_rsa`, `*.crt`) or `.npmrc` — which is where an npm auth token +would land. Nothing has been committed (APPS-021); this is prevention, and it is prevention in the template every app +author copies. Neither example ships a `.dockerignore`, so an author who broadens the template's `COPY src/` to +`COPY . .` ships `.git/` and any local `.env` inside the image. + +**Fix.** Broadened `.gitignore`; a `.dockerignore` added to both examples. + +--- + +### APPS-016 — Sun position evaluated once at noon · **Low** · Confirmed + +**Where:** [`examples/…/src/js/prayer.js:89`](../../examples/prayer-times-display/src/js/prayer.js#L89) + +One `sunPosition()` evaluation at local apparent noon serves every prayer. Declination moves up to ~0.4°/day, so at +Fajr or Isha (6+ hours from noon) it is off by ~0.1°, which the file's own header ("well under a minute") understates +at higher latitudes near the equinoxes, where d(time)/d(declination) grows. + +The underlying astronomy is otherwise sound and I checked it line by line: the USNO low-precision solar position, the +`equation = q/15 - fixHour(ra)` wrap (harmless — the downstream `fixHour(12 - eqt)` absorbs the ±24 h ambiguity), the +Asr shadow-factor formulation, and the 0.833° sunrise/sunset refraction constant are all correct. + +**Fix.** One refinement iteration per prayer — re-evaluate `sunPosition` at each prayer's first-pass fractional day, +the standard approach. Sub-minute change at mid-latitudes; larger and more correct at high latitudes. + +--- + +### APPS-017 — Midnight-crossing Isha mis-selects the next prayer · **Low** · Confirmed + +**Where:** [`examples/…/src/js/app.js:128-156`](../../examples/prayer-times-display/src/js/app.js#L128-L156) + +`prayerTimes()` returns raw decimal hours that may exceed 24 (Isha after local midnight, common far west in a +timezone or at high latitude) or go negative. `formatClockTime` normalises for *display*, but `findActiveAndNext` +compares the un-normalised values against `nowHours` (0–24). Just after local midnight the day key rolls over, the +table is recomputed, and the new `isha ≈ 24.3` still tests `> nowHours`, so the board announces "Next: Isha" for a +time that passed twenty minutes earlier. + +**Fix.** Normalise to a monotonic same-day timeline before comparison, and carry yesterday's Isha so the post-midnight +window resolves to the correct active prayer. + +--- + +### APPS-018 — Prayer grid rebuilt every second · **Low** · Confirmed + +**Where:** [`examples/…/src/js/app.js:77-99`](../../examples/prayer-times-display/src/js/app.js#L77-L99), driven by +`setInterval(tick, 1000)` at `:198` + +`renderCards()` does `grid.innerHTML = ''`, then six `createElement` plus six `innerHTML` assignments — a full parse, +layout and paint of the entire grid, **86,400 times a day**, forever, on a Raspberry Pi driving a TV. Only the +countdown text actually changes each second. The audit brief's low-power-hardware concern, on the exact hardware +`CLAUDE.md` §11 targets. + +**Fix.** Build the six cards once; per tick only update `textContent` and toggle the two state classes. No visual +change. + +--- + +### APPS-019 — `parking-attendant` image is not digest-pinned · **Low** · Confirmed · **Deferred** + +**Where:** [`registry.yaml:50-53`](../../registry.yaml#L50-L53). The build says so itself: + +``` +⚠ parking-attendant: image "ghcr.io/sybutter/openmasjidparkingattendant:0.2.1" is not digest-pinned — + a moved tag could repoint it to a backdoored image. +``` + +The only third-party entry (`SyButter/…`) is the only one not meeting the digest-pinning control the repo documents. +Its registry `commit:` pin is correct, so the *compose* is immutable — but the image tag that compose names is not, so +the owner (or anyone who compromises that GHCR account) can repoint `:0.2.1` at a different image and every masjid +pulls it on next install or recreate. + +**Deferred deliberately, not overlooked.** Fixing it means either editing `registry.yaml` — which triggers the +production rebuild-and-publish path this audit is forbidden to fire — or asking the third-party author to digest-pin +their own compose. It is in `ACTION_REQUIRED.md` with the resolved digest for you to apply. + +--- + +### APPS-020 — No tests, lint, or type checking · **Info** · Confirmed + +`package.json` has exactly one script (`build`). There is no test runner, no linter, no type checker, and no CI job +that runs any — `.github/workflows/` contains only the catalog build and the CLA bot. `scripts/validate-compose.mjs` +is described in `CLAUDE.md` §10 as "the catalog's safety gate" with a **DO-NOT-REGRESS** invariant, and it has zero +tests; the sweep that invariant records was verified by hand. + +This is also what made this audit's ship gate unmeetable as written: there was no test suite to keep green. + +**Fix.** A `node:test` suite (built in, zero new dependencies): 60 cases over `validateCompose` covering every +directive class including all new rules and a regression test per finding, plus prayer-engine tests pinning the +high-latitude behaviour and known-good times. `npm test` and `npm run lint` (a `node --check` pass over every script) +wired into `build-catalog.yml` as a gate that must pass **before** the catalog is published. + +--- + +### APPS-021 — Secrets: clean · **Info** · Confirmed · No action + +All **475 commits** on all branches, content-scanned (`git log --all -p -G`) for 18 credential patterns: AWS access +keys, GitHub PAT/OAuth/fine-grained tokens, Stripe live/test/restricted keys and webhook secrets, Slack tokens, PEM +private keys and certificates, Google API keys, JWTs, SendGrid keys, npm tokens, and Postgres/MySQL/MongoDB +connection strings with embedded passwords. + +``` +clean: AKIA[0-9A-Z]{16} clean: sk_live_… clean: BEGIN … PRIVATE KEY +clean: ghp_… gho_… github_pat_… clean: whsec_… clean: postgres(ql)?://user:pass@ +clean: AIza… eyJhbGciOi… SG\.… clean: xox[baprs]-… clean: npm_… (18/18 clean) +``` + +**No hits.** No `.env`, certificate, backup or database dump has ever been committed — the full historical file list +was enumerated and reviewed.

The `if:` gate restricts comment handling to two literal strings. +`actions: write` is required by the official setup to re-run the check after signing, and the header documents why. +Untrusted input reaches a pinned third-party action, not this repo's code. + +Residual risk, recorded not fixed: the permissions are broad enough that a future compromise of that action would be +serious, and the elevated `PERSONAL_ACCESS_TOKEN` is passed when set. Consider Dependabot on +`.github/workflows/**` so the pin is maintained rather than frozen. + +--- + +### APPS-023 — Image template re-pushes the same version tag, and `:latest` · **Low** · Confirmed + +**Where:** [`examples/…/build-image.yml:18-20,58-60`](../../examples/prayer-times-display/.github/workflows/build-image.yml#L18-L20) + +The template triggers on `push: branches: [main]` and pushes `ghcr.io//:` plus +`:latest`. Since the version is read from `manifest.yaml`, **every commit to `main` overwrites the existing version +tag with different content** — the template manufactures exactly the moved-tag condition the rest of the repo warns +about at length (`CLAUDE.md` §10, `registry.yaml`'s header, and the build's own ⚠ output). An app pinned by tag +silently changes underneath the catalog; only digest-pinned entries are protected. + +**Fix.** Build on `main` but **push only on `v*` tags**; drop `:latest`; and print the resulting image digest at the +end of the run so the author can paste `@sha256:…` into their compose, which is what the docs ask them to do. + +--- + +## Coverage and gaps + +**Assessed in full:** all 38 tracked files; all 475 commits of history (content-scanned, not just filenames); both +workflows; the registry and the generated catalog; `build-catalog.mjs` and `validate-compose.mjs` line by line; both +example apps including the four recovered files each; the prayer engine's astronomy checked term by term against the +USNO low-precision method; `npm audit` and the dependency tree; every documentation file for claims that contradict +the code.

The one `innerHTML` use (`renderCards`) interpolates only hardcoded labels and numbers. No + `eval`, no `dangerouslySetInnerHTML`, no `document.write`, no inline handlers, no remote script or font origins. +- **Shell injection in the entrypoints** — `esc()` escapes backslashes and quotes and strips CR/LF, and values enter + via `$(…)` command substitution whose *result* the shell does not re-expand, so the unquoted heredoc is safe. +- **YAML deserialisation** — `yaml@2.9.0` constructs no arbitrary objects; an alias bomb is caught by its own + `maxAliasCount` and degrades to the raw-regex path, which still rejects `privileged` (verified). +- **No RCE path in the build** — fetched content is parsed, never evaluated; no `child_process`, no dynamic + `import()` of remote data, no prototype-pollution sink (fetched objects are read field-by-field, never merged). +- **Compose checks that do work** — Docker socket (including `/run/docker.sock` and `/var/run` parent mounts), + `privileged` in all five truthy spellings, host/container `network_mode`/`pid`/`ipc`, `userns_mode`/`cgroup`/`uts: + host`, `devices`, `device_cgroup_rules`, `volumes_from`, `env_file` escapes, `extends`/`include`, `build:`, YAML + merge keys, sensitive-root and `..` bind mounts, external and renamed volumes, and file-based `secrets`/`configs` + pointing outside the app folder. This is a well-built gate; the findings are its edges. +- **Not applicable, absent by design** — there is no SQL, no ORM, no HTTP server, no session or token handling, no + password storage, no CSRF or CORS surface, no file upload, no archive extraction, no cryptography, and no SSRF sink + beyond the two fixed `raw.githubusercontent.com`/`api.github.com` hosts. Phases 2, 4 and 7 of the brief are largely + vacuous *for this repository* and I have not manufactured findings to fill them. +- **Mobile/client concerns from the addendum** — assessed against what exists. These are nginx-served static web + apps, not native mobile apps: there is no WebView, no `addJavascriptInterface`, no deep link or URL scheme, no + exported component, no OS backup surface, no third-party SDK, and no permission manifest. **No secret or API key is + present in either shipped bundle** — every `OMOS_CONFIG` value is non-sensitive display configuration.

The reject is correct either way. +2. **How the platform reacts to a duplicate `com.docker.compose.project` label** (APPS-004) — the rule is confirmed + unenforced here; the consequence needs platform verification. +3. **Whether the platform's Markdown renderer sanitises `description`** (APPS-014) — determines whether hostile + manifest Markdown is cosmetic or XSS in the dashboard. +4. **Whether the platform's `.env` writer quotes values** (APPS-014) — determines whether a newline in + `settings[].default` is a real injection. +5. **Live drift between this validator and the platform's `apps/compose-validate.ts`** — `CLAUDE.md` §10 requires + lockstep and I could only verify one side. A shared fixture suite is the durable answer. +6. **Whether `CATALOG_PUSH_TOKEN` is scoped as narrowly as its comment claims** — repository secrets are not readable. +7. **Runtime behaviour on real hardware** — no Raspberry Pi or OpenMasjidOS instance was available, so APPS-018 is + reasoned from the code path, and the restored examples were verified by static review and build, not by rendering + on a TV. + +All items 1–4 have their platform-side counterpart written up in `ACTION_REQUIRED.md` under "Cross-repo", per Tier 3.

The attacker's own ref (main) is mutable, so content could change after review and the unattended nightly rebuild would republish it -- and CATALOG_PUSH_TOKEN bypasses branch protection, so no second human gate stood in the way. Validation now runs before any URL is built (scripts/registry-validate.mjs, split out so it is testable -- importing build-catalog.mjs runs the build): - repo must be exactly / from [A-Za-z0-9._-] - ref must be a plain git ref and contain no .. - path must be a relative subpath with no .. segment - all three reject whitespace, control chars and URL punctuation - rawBase() re-validates and asserts the assembled URL is still on raw.githubusercontent.com under ///, so the traversal cannot be reintroduced by a caller that forgets to validate Verified: 119 tests pass (13 new, incl. one that executes the pre-fix URL to document the escape); lint passes; catalog.json rebuilds byte-identical, so the platform contract is untouched.

This is valid Docker Compose (confirmed against Docker Compose v5.3.1) and passed with zero errors AND zero warnings: services: a: networks: [omos_internal] networks: omos_internal: external: true `external: true` uses the network name verbatim and `name:` overrides the project-scoped name, so either places the container on a pre-existing network -- including the platform's own, where the core API and other apps' containers listen. classifyVolumeSource() only ever sees volume sources, so nothing looked at this. The asymmetry with the volume rule is what makes it an oversight rather than a decision. Now rejected, mirroring the volume rule exactly: - any top-level network with `external:` (short or { name } form) - any top-level network with an explicit `name:` override - a distinct message when the target matches ^omos[-_], because that one reaches the platform - `driver: host` / `driver: none` - a service joining a network the file never declares (compose would resolve it against pre-existing networks) Ordinary project-scoped networks, aliases, and composes with no networks: block at all are unaffected -- all covered by tests. Per Tier 3 the matching change to the platform's apps/compose-validate.ts is NOT made here; it is recorded in docs/audit/ACTION_REQUIRED.md under Cross-repo. What is reachable on an omos_* network could not be verified from this repo and is flagged as such in the audit. Verified: 129 tests pass (10 new); all five live app composes still pass; catalog.json rebuilds byte-identical.

APPS-004 (Medium) - CLAUDE.md section 4C forbids discovery labels and docs/BUILDING_AN_APP.md:573 states they are "Rejected at build AND at install". Nothing here ever read labels, so the documented guarantee was not real and this passed clean: labels: com.docker.compose.project: omos-donations com.openmasjid.trusted: "true" CLAUDE.md section 2.5 says platform discovery is by com.docker.compose.project=omos-, so an app claiming another app's project label can confuse platform inventory, lifecycle and uninstall - it may be listed, stopped or removed as part of that app. Now rejected (case-insensitively) on services, service build, networks, volumes, secrets and configs, in both the map and "k=v" list forms. An app's own labels, including org.opencontainers.*, are unaffected. The precise platform-side consequence of a duplicate project label could not be verified from this repo and is recorded in ACTION_REQUIRED.md. APPS-011 (Low) - cgroup_parent was unchecked although `cgroup: host` was rejected, and both are the same class. It places the container outside the cgroup slice the platform assigns, escaping the memory and CPU limits that keep a Raspberry Pi responsive. Now an error. sysctls is now a warning rather than an error: Docker only permits namespaced sysctls without --privileged, so the reach is the container's own namespace - worth surfacing, not worth failing a legitimate app over. APPS-012 (Low, NOT exploitable) - cap_add, security_opt and group_add were gated on Array.isArray(), so a scalar skipped the check entirely, while the neighbouring devices and volumes_from checks handled both shapes. I first read this as a bypass; Docker Compose v5.3.1 settled it: cap_add: SYS_ADMIN -> services.a.cap_add must be a array security_opt: seccomp=... -> services.a.security_opt must be a array group_add: docker -> services.a.group_add must be a array So such a compose fails at install anyway and no privilege is gained. It is still fixed, because CLAUDE.md section 10 makes lockstep with the platform's independent validator an invariant, that validator may normalise shapes differently, and a safety check should not depend on YAML shape. Downgraded to Low in the report accordingly. Verified: 158 tests pass (13 new); all five live app composes still pass - they use the list form with cap_drop and no-new-privileges, and set no labels, cgroup_parent or sysctls; catalog.json rebuilds byte-identical.

Two problems, both reachable from untrusted app-repo content. 1. Quadratic regex. The merge-key scan was /(^|\n)\s*<<\s*:/. Because \s also matches \n, the (^|\n) alternation and the \s* quantifier overlapped: a match could begin at every newline and \s* then ran to end-of-input before failing. Measured on the old pattern against attacker-controlled compose text: 20,000 chars 98.8 ms 80,000 chars 1611.1 ms 160,000 chars 6431.7 ms 320,000 chars 25712.5 ms (~4x per doubling) Replaced with the anchored /^[ \t]*<<[ \t]*:/m, which is linear because a merge key can only be preceded by spaces or tabs on its own line: 320,000 chars 0.235 ms (about 100,000x faster) Proven equivalent on every spelling that matters - indented, tab indented, at column 0, and "<< :" with a space before the colon - and on a negative case. Three of those are now tests. 2. Unbounded, untimed fetch. fetchText had no timeout and no size limit; res.text() buffered whatever the remote sent, so a slow server could hang the job to the 6-hour Actions ceiling and a huge body could exhaust its memory. Now: - AbortSignal.timeout(20s) on both fetchText and resolveRefToSha - a 2 MiB ceiling enforced while streaming the body, so it stops at the limit instead of discovering the size after buffering - content-length rejected up front when it already exceeds the cap - a separate 64 KiB cap on the compose itself, since that text is embedded verbatim into catalog.json for every install With the 2 MiB fetch cap in place the worst case that can now reach the validator costs ~1.2s, and that residual is the YAML parser walking the document, which is linear in size: 1 MiB mergeKeyRegex 0.96ms yamlParse 594ms 2 MiB mergeKeyRegex 2.44ms yamlParse 1222ms 4 MiB mergeKeyRegex 4.13ms yamlParse 2450ms Real limits are far above real content: the largest live compose is well under 10 KB and the largest manifest a couple of KB. Verified: 161 tests pass (4 new). The linearity test asserts the shape - 4x input must not cost 16x - rather than an absolute wall-clock number, so it will not flake on shared CI. Full build against all five live repos still succeeds and catalog.json rebuilds byte-identical.

Context for the severity: catalog.json on main IS the artifact the platform fetches, and this workflow regenerates and pushes it unattended on a cron, using CATALOG_PUSH_TOKEN, a PAT chosen specifically to bypass branch protection. It is the highest-leverage position in the repository. APPS-005 (Medium) - it ran `npm install`, which unlike `npm ci` may resolve a newer version inside the declared "^2.5.0" range and rewrite the lockfile. Demonstrated: a plain `npm install` on a clean tree modified package-lock.json. So an unreviewed dependency release could execute in this job and then publish with it. Now `npm ci`, which installs exactly what the lockfile pins - verified it succeeds and leaves the lockfile untouched. Added `cache: npm` to setup-node. APPS-006 (Medium) - seven actions were on mutable major tags. Moving a tag is the exact supply-chain attack the rest of this repo warns about at length for registry refs and image tags. The catalog workflow's two mattered because of the PAT; the five in the copied image-build template mattered more, because that job holds packages: write and pushes the image masjids pull - docker/build-push-action and docker/login-action among them. cla.yml already pinned by SHA, so this applies an existing in-repo convention rather than inventing one. Pinned, with the version kept in a trailing comment: actions/checkout -> 11d5960a326750d5838078e36cf38b85af677262 # v4 actions/setup-node -> 49933ea5288caeca8642d1e84afbd3f7d6820020 # v4 docker/setup-qemu-action -> c7c53464625b32c7a7e944ae62b3e17d2b600130 # v3 docker/setup-buildx-action -> 8d2750c68a42422c14e847fe6c8ac0403b4cbd6f # v3 docker/login-action -> c94ce9fb468520275223c153574b00df6fe4bcc9 # v3 docker/build-push-action -> 10e90e3645eae34f1e60eeb005ba3a3d33f178e8 # v6 Pinned to the tip of the SAME major each file already used, so no behaviour changes. Newer majors exist (checkout v7, setup-node v7, docker/* v4/v7) but a major bump is a Tier 2 change and is listed in ACTION_REQUIRED.md instead of made here. APPS-020 (Info) - the publish step is now gated on `npm run lint` and `npm test`. scripts/validate-compose.mjs is described in CLAUDE.md section 10 as the catalog's safety gate with a DO-NOT-REGRESS invariant; proving it works before regenerating the production artifact is the point of having the suite at all. lint also asserts catalog.json still matches the platform contract in CLAUDE.md section 2, so a shape regression fails the build instead of shipping. Verified: all four workflow files parse and their step lists are correct; `npm ci` exits 0 and does not mutate the lockfile; every action in the repo is now SHA-pinned (grep for a bare @vN finds nothing); 161 tests and lint pass.

Concrete consequences: - `name` was only tested for truthiness, then apps.sort() called a.name.localeCompare(b.name). A numeric or object name threw a TypeError and broke the build (asserted in a test). - wrong types silently violated the platform contract in CLAUDE.md 2.3, which fixes settings as an Array and ports as [{container: number}]. - settings[].key was not checked as an environment-variable name, and settings[].default was not checked for newlines - although CLAUDE.md 7 requires single-line values precisely because the platform writes them to .env as KEY=VALUE. A newline there is an .env line injection. - no length limit at all on a field embedded in the file every masjid fetches. Now validated: strings must be strings and are capped (name 120, tagline 200, description 16 KiB - the largest live description is ~1.7 KB, so the caps are far above anything real); settings must be a list of objects with an ^[A-Za-z_][A-Za-z0-9_]*$ key, no duplicates, a known type, options present for select, and a single-line scalar default; ports[].container must be an integer in 1..65535; icon/screenshots must be relative subpaths with no ".." and no scheme. description stays multi-line, since it is markdown. Scope note, per Tier 3: `description` is rendered as markdown on the platform's app detail page, so whether hostile markdown is merely ugly or is XSS in the dashboard depends on the platform's renderer, which I cannot see from this repo. Likewise whether the platform quotes .env values. Implemented the half that belongs here - reject it at the catalog boundary - and recorded both platform-side questions in ACTION_REQUIRED.md rather than guessing. Verified: 200 tests pass (63 new, covering every accepted and rejected shape). All five live manifests still validate and catalog.json rebuilds byte-identical, so nothing currently listed is affected.

What the first draft got wrong: it called APPS-003 "the finding to read if you care about harm" and "the most important unfixed finding", which reads as though the prayer engine masjids actually run is broken. It is not. The facts, checked against the live catalog: - the defect is in examples/prayer-times-display/src/js/prayer.js, a REFERENCE TEMPLATE in this repo - prayer-times-display is commented out in registry.yaml:55-56, so it is in no catalog and no masjid can install it - prayer times for real installs belong to the shipped `display` app, OpenMasjidDisplay v0.65.0, whose own manifest description says it renders "prayer clocks calculated on the device" with Adhan and Iqamah times. That engine is in ITS OWN repository behind a digest-pinned image, has no catalog settings (configured in its own control panel), and is a much larger codebase than this static nginx template. And the part that needed saying explicitly: I never read OpenMasjidDisplay's source. The catalog build fetches only each app's manifest.yaml and docker-compose.yml; the engine is inside the image. Claiming the same bug there on this evidence would be a fabricated finding. It is now recorded in ACTION_REQUIRED.md as a cross-repo CHECK TO RUN, with the exact test - MWL times for London (51.5074, -0.1278) on 21 June; if Fajr equals Isha, or Fajr lands near 01:00, it has the same clamp. Severity: Medium, not High. Nothing here ships, and this is not the engine masjids use, so neither the Critical criterion ("wrong prayer times shipped to users") nor High applies. It is latent - harmful once an author copies the template, which CLAUDE.md 1 and 4A and docs/BUILDING_AN_APP.md all tell them to do. The verified numbers are unchanged (London 21 June still returns Fajr 01:02 and Isha 01:02, which is impossible). Only the reach was overstated. Severity totals become: High 2, Medium 8. APPS-001 stays High and remains the most important finding in this repo.

Don't add real app source here." Section 11 (quality bar: design language, RTL, "prayer times get the same scrutiny as security bugs") and section 14 (definition of done for an app) also read as though they applied to this tree. Combined with "complete, working", the natural reading is that examples/ is a maintained product held to that bar - so finding it broken looks like a bug to fix here. It is not: nothing under examples/ is catalogued, built, tested or run by anyone. Changes: - section 1: examples/ is "illustrative scaffolding only" - skeletons showing the SHAPE an app repo needs. Explicitly not in the catalog, not built, not tested, not released, not run by any masjid. Once copied it is the author's code in the author's repo. - section 1 "does NOT contain": adds that this repo does not own app behaviour or correctness - prayer times, Hijri, Qibla, Zakat maths, UI, RTL - and names OpenMasjidDisplay as the owner of the prayer clocks masjids actually run, noting that changing examples/ cannot fix or break it. - section 15: two new rules. Do not modify app source in this repo, INCLUDING examples/, which is out of scope for reviews, audits, refactors, test coverage and bug fixes - say so and stop rather than fixing it as a side quest.

Pinning every action to a commit SHA stops a moved tag reaching the workflow that publishes catalog.json, but it also freezes the version - so the fix introduces a new failure mode: a pin nobody updates becomes a stale pin with known bugs. Dependabot resolves that by opening a reviewable PR that moves the SHA and its trailing version comment together. Watches this repo's tooling only: github-actions plus the single npm runtime dependency. It does NOT watch examples/, which is illustrative scaffolding rather than software this repo maintains (CLAUDE.md section 1), and whose workflows never run from here. A major bump to yaml is excluded from automation: it is the library the build parses untrusted app-repo YAML with, so that is a review decision.

REMEDIATION.md - what shipped, per commit: what changed, why the fix works, how it was verified, with the real npm ci / audit / lint / test / build output pasted in rather than summarised. Leads with the three behaviour-changing items (the build now rejects inputs it used to accept, CI gates publication on lint+tests, npm install became npm ci). Includes a rollback command per finding, the two ordering constraints between them (APPS-014 before APPS-001, the CI gate before the test infra), and how to revert the whole run to pre-audit-2026-07-31. Also records the two mistakes I made and corrected, so the rest can be judged in that light. ACTION_REQUIRED.md - only-you items. No credential needs rotating (475 commits, 18 patterns, zero hits) and no history rewrite is needed or recommended; the priority list exists only in case one is ever suspected. Cross-repo requests are stated as requests, not done deals: four compose checks for the platform to mirror so CLAUDE.md section 10 lockstep holds, three platform questions that would settle a severity here, and a digest pin needed in the parking-attendant repo which cannot be done from registry.yaml. Plus assumptions to disagree with, and what to do if main breaks after merge. findings.json - 19 findings plus 4 withdrawn, same schema as the other repo audits so they merge. Cross-checked: the finding set matches the report table exactly, the totals block matches the per-finding counts, and every fixed finding names its commit while no deferred one does. Report scoping finished in this commit: the three prayer-time/Hijri findings and the disproved midnight-Isha one are removed from the findings table and detail sections, the severity counts corrected to 19, and the threat model and coverage sections rewritten so examples/ is stated as deliberately not assessed rather than silently absent. The executive summary now leads on the pattern that actually matters here - three controls documented as enforced that were not implemented.

The build says so on every run: + +``` +⚠ parking-attendant: image "ghcr.io/sybutter/openmasjidparkingattendant:0.2.1" is not digest-pinned + — a moved tag could repoint it to a backdoored image. +``` + +Its registry `commit:` pin is correct, so the *compose* is immutable — but the image tag that compose +names is not, so the owner (or anyone who compromises that GHCR account) can repoint `:0.2.1` at +different content and every masjid pulls it on the next install or recreate. + +**Why I did not fix it:** the digest must go in **that repo's** `docker-compose.yml`; there is no +field in `registry.yaml` that can pin it. Ask the author to change `image:` to +`ghcr.io/sybutter/openmasjidparkingattendant:0.2.1@sha256:`, then bump the `commit:` pin here. +Get the digest with: + +```bash +docker buildx imagetools inspect ghcr.io/sybutter/openmasjidparkingattendant:0.2.1 --format '{{.Manifest.Digest}}' +``` + +### 4d. `OpenMasjidDisplay` — one optional check, **not a finding** + +Recorded for completeness only, and explicitly **not** a claim about that repo. I never read its +source: the catalog build fetches only each app's `manifest.yaml` and `docker-compose.yml`, so its +application code was never visible to this audit. + +While reading the *reference scaffolding* under `examples/`, I noticed a pattern worth a one-minute +check in any prayer-time implementation: clamping the hour-angle equation into `[-1, 1]` instead of +reporting "no solution" turns persistent-twilight nights (normal above ~48°N in summer) into a +confident wrong time. **If** `display` computes prayer times this way, the symptom is distinctive: + +> Compute MWL times for London (51.5074, −0.1278) on 21 June. If **Fajr equals Isha**, or Fajr lands +> near 01:00, the clamp is present and a high-latitude rule (Angle-Based / Middle of Night / +> One-Seventh) is needed. + +That is a matter for `OpenMasjidDisplay`'s own audit, by whoever can read that code. Prayer-time +correctness is not this repository's concern (`CLAUDE.md` §1, corrected in this branch). + +--- + +## 5. Infra / provider / policy + +Nothing was changed; these need your judgement. + +1. **Consider whether the auto-publish design is what you want** (no change made, no finding filed — + it is a deliberate architecture choice). Today an unattended cron can publish to every masjid + using a protection-bypassing PAT. It now runs behind lint + tests, and the registry is fully + `commit:`-pinned, so content is stable. If you want a stronger gate, the options are: publish only + on `workflow_dispatch`/`repository_dispatch` and let cron open a PR instead; or require a review + on catalog-only commits. Both cost you latency on app releases. +2. **Major action upgrades.** I pinned to the tip of the **same major** each workflow already used — + deliberately no behaviour change. Newer majors exist (`actions/checkout` v7, `actions/setup-node` + v7, `docker/*` v4–v7). A major bump is a Tier 2 change; Dependabot (added in this branch) will now + propose them for review. +3. **Enable Dependabot alerts / security updates** in repo settings if not already on. The config + added here covers version updates; alerts are a separate toggle. + +--- + +## 6. Assumptions I made — flag any you disagree with + +1. **`examples/` is out of scope.** Treated as illustrative scaffolding, not maintained software, per + your direction and now per corrected `CLAUDE.md` §1/§15. Consequence: the two reference apps are + **still incomplete on `main`** (`src/index.html`, `src/css/style.css`, `icon.svg`, + `screenshots/1.svg` were dropped by commit `cabcbae` and never restored), so an author who copies + one gets a non-serving app. Recorded as APPS-008, unfixed by choice. +2. **New rejections must not break a listed app.** Every new check was verified against all five live + composes before shipping, and `catalog.json` rebuilds byte-identical after every commit. +3. **Caps are generous, not tight.** `description` 16 KiB (largest live: ~1.7 KB), compose 64 KiB + (largest live: well under 10 KB), fetch 2 MiB, fetch timeout 20 s. Chosen so nothing real is + affected; tighten if you prefer. +4. **`path:` with a leading `/` is now rejected rather than silently stripped.** No entry uses it. +5. **APPS-022 accepted as-is.** `cla.yml` uses `pull_request_target` with `actions: write`, triggered + by any comment — but it never checks out PR code and runs one SHA-pinned action, which is the + official setup. Not changed. +6. **The `cla` status check.** The PR will need it. As a maintainer you are on the workflow's + allowlist, so it should pass without action. + +--- + +## 7. If `main` breaks after merge + +```bash +# Find the merge, revert it, push the revert. +git -C OpenMasjidAPPS log --oneline -5 main +git -C OpenMasjidAPPS revert -m 1 +git -C OpenMasjidAPPS push origin main + +# Or reset main to the exact pre-audit state (the tag is local until you push it): +git -C OpenMasjidAPPS push origin pre-audit-2026-07-31 # optional: publish the tag first +git -C OpenMasjidAPPS reset --hard pre-audit-2026-07-31 # 4f4a7f0486b4228c630156bf5b51e162f24c34eb +``` + +Then confirm `catalog.json` on `main` is back to the pre-audit content — that is the file every +masjid reads.

Defence at both the input and the output. +- **APPS-002** — the validator already forbade attaching to storage an app doesn't own; networks were + simply never inspected, because `classifyVolumeSource` only ever sees volume sources. The new check + is the same rule applied to the same shapes (`external:` short and long form, `name:` override), + with a distinct message for `omos[-_]*` because that target reaches the platform. +- **APPS-004** — the rule was documented as enforced and wasn't implemented at all. Now checked on + every place compose accepts labels, in both syntaxes, case-insensitively. +- **APPS-005** — `npm install` may resolve inside `^2.5.0` and rewrite the lockfile; `npm ci` cannot. + In a job holding a protection-bypassing PAT, that difference is the whole point. +- **APPS-006** — a tag is mutable, a SHA is not. Pinning removes the moved-tag path; Dependabot stops + the pin becoming a stale-version problem instead. +- **APPS-007** — the old pattern was quadratic because `\s` matches `\n`, so `(^|\n)` and `\s*` + overlapped and a match could start at every newline. The anchored `^[ \t]*<<[ \t]*:/m` is linear and + matches the same directive (proved equivalent on four spellings). Streaming the body with a byte + budget stops a large response *while* it arrives rather than after buffering it. +- **APPS-011/-012** — `cgroup_parent` escapes the cgroup slice the platform assigns, which is the same + class as the already-rejected `cgroup: host`. The scalar normalisation is hygiene, not a fix for an + exploit: Docker Compose rejects scalars there, so nothing was reachable. +- **APPS-014** — untrusted manifest fields reached `catalog.json` unchecked; `name` was truthiness-only + and then sorted with `localeCompare`, so a numeric name crashed the build. Types, lengths, env-key + syntax and port ranges are now checked at the boundary the catalog owns. + +### Two mistakes I made and corrected — visible so you can judge the rest + +1. **APPS-017 was wrong.** I claimed midnight-crossing Isha mis-selected the next prayer, implemented + a fix, then simulated a full day comparing old and new: **zero** observable difference, because the + `order` array already checks Fajr before Isha. I reverted the fix rather than ship an unnecessary + change, and withdrew the finding. +2. **A font change I made caused a regression, caught before commit.** Adding a Naskh face to the + global font stacks made *English* render in it (a headless render showed `fontStartsWith: "Noto + Naskh Arabic"` on an English page). Scoped it to `:lang(ar)` etc. instead. That work is no longer + on this branch — `examples/` is out of scope — but it is the reason I now check computed output + rather than assuming a CSS edit is inert. + +Also worth knowing: **my own test caught my own error.** The equinox invariant initially asserted a +12.000 h day at the equator; the code returned 12.111 h, which is *correct* — sunrise/sunset are taken +0.833° below the horizon, so the apparent day is longer by `2 × 0.833 / 15 = 0.111 h`.

The gate added earlier lives in build-catalog.yml, which only triggers on push to main (plus cron and dispatch). On main the regenerated catalog.json is published immediately - the platform fetches that raw file with no deploy gate - so a problem caught there is caught after it is already live to every masjid. The check was in the wrong place. This workflow moves it in front of the merge: npm ci, npm run lint, npm test on every pull request targeting main. lint also asserts catalog.json still matches the platform contract (CLAUDE.md section 2), so a shape regression is caught at review time. Details worth noting: - permissions: contents: read only. It reads code and reports a status; it never needs a token that can write or publish. - concurrency group with cancel-in-progress, so a force-push supersedes the previous run instead of queueing. - actions pinned to the same SHAs as build-catalog.yml. - npm audit runs advisory (continue-on-error): a fresh advisory in a transitive package should be visible in the log but must not block an unrelated catalog PR. - npm run build is deliberately NOT run here. It fetches every listed app repo (network, rate limits) and rewrites catalog.json, which must only ever be regenerated by build-catalog.yml on main. Verified: workflow parses, triggers and permissions are as intended, and lint plus 139 tests pass locally on this branch.

From 7ecae8b584e60a24c00b83122dd3604ade2edf5b Mon Sep 17 00:00:00 2001 From: hasan-ismail Date: Fri, 31 Jul 2026 22:13:50 -0400 Subject: [PATCH 16/16] fix(test): make npm test work on Node 20, not just Node 24 [APPS-020] The new PR workflow failed on its first run and caught a real bug in my own test script: > node --test "scripts/__tests__/*.test.mjs" Could not find '/home/runner/work/.../scripts/__tests__/*.test.mjs' ##[error]Process completed with exit code 1 Node only expands a quoted glob passed to --test from v22 onward. I wrote and verified that script on Node 24 locally; CI runs Node 20, where the pattern is taken literally as a filename. So `npm test` was silently broken on the runtime that actually matters, and the audit's own test evidence had only ever been produced on the wrong Node version. Checked every candidate against BOTH runtimes rather than assuming: Node 20 Node 24 node --test 139 pass 139 pass node --test scripts/__tests__ 139 pass 0 pass, fail node --test "scripts/.../*.test.mjs" not found 139 pass Only the bare `node --test` works on both, so that is what package.json now uses. It recursively finds files matching the *.test.mjs convention from the repo root and skips node_modules, which covers scripts/__tests__ today and anything added later without needing the script updated again. Verified: 139 tests pass under Node 20 in a container and under Node 24 locally; lint passes. This is exactly the failure the PR workflow was added to catch, and it caught it before the branch could be merged - the previous arrangement, with checks only on push to main, would have gone red after the catalog was already republished.
