From 88f4691dfa72db9fe68e5740fa7c046d77460034 Mon Sep 17 00:00:00 2001 From: Jules Lemee Date: Fri, 17 Jul 2026 14:25:53 -0700 Subject: [PATCH 1/9] turnstile-spin: guide token reset after submit to fix V2 double-redemption MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Turnstile tokens are single-use. When siteverify returns success:false and the user retries, the browser resubmits the same cf-turnstile-response and Cloudflare's edge rejects it with timeout-or-duplicate. V2 telemetry since the 2026-07-14 launch shows 4.86% sv_fail rate, of which 99% (123/124) are double redemptions — 5x the V1 baseline of 0.9%. Add reset-on-submit guidance to the canonical frontend snippet in SKILL.md and to each framework reference so the widget re-solves before the retry. Also add a 'Token lifecycle' paragraph explaining the single-use contract. - SKILL.md: id=cf-form + reset script; Token lifecycle paragraph - vanilla-html: main HTML + AJAX variant get reset calls - nextjs-app: handleSubmit resets on !data.ok; Server Action variant covers useActionState error branch - nextjs-pages: reset script wrapped in -
+
+ ``` Backend: use the canonical siteverify fetch from Step 9 inside the existing handler. Read the token from `req.body['cf-turnstile-response']`, gate on `success === true`, and leave the rest of the handler alone. If the existing handler was a stub, Spin leaves it a stub gated on success. The user can replace the stub later; that's not Spin's job. +**Token lifecycle: tokens are single-use.** A `cf-turnstile-response` token is redeemed exactly once at siteverify. If the server rejects (non-2xx or `success: false`), the browser still holds the redeemed token in the DOM; a naive retry submits the same token and Cloudflare's edge rejects the second attempt with `timeout-or-duplicate`. Always call `window.turnstile.reset()` before the user is allowed to retry. The framework references show the per-framework hook (submit listener for native forms, response handler for AJAX/SPA submits, `onError` for React components). + ## Migrating from another CAPTCHA During the Step 6 codebase scan, also look for existing reCAPTCHA or hCaptcha.

The bot's critical (EXIT trap fires in $() subshell) is a false positive verified with a bash test: subshells reset their parent's traps per the bash manual, so $tmp survives curl $() calls and the trap only fires on outer-script exit. - All scripts: 'command -v python3' guard at top; emit structured JSON error on missing prerequisite instead of raw shell error. - All scripts: header comments now document exit 2 (invalid usage) in addition to exit 0 (success) and exit 1 (failure). - widget-create.sh, validate.sh, fetch-secret.sh, auth-probe.sh: Authorization header written to mode-600 tempfile, curl reads it via '-H @file'. Bearer token never appears in argv. - validate.sh: Turnstile secret written to mode-600 tempfile, curl reads it via --data-urlencode 'secret@file'. Secret never appears in argv. - validate.sh: strip whitespace from each expected-domains token so '--expected-domains "a.com, b.com"' matches correctly. - fetch-secret.sh, auth-probe.sh: guard 'errors[0]' with '(errors[0] or {})' before .get() to survive non-dict error entries. - All parse blocks: 'isinstance(data, dict)' check after json.loads; emit structured error output when response is not a JSON object. - persist-skill.sh: catch OSError (not just FileNotFoundError) so NotADirectoryError/PermissionError on the scripts dir emit 'scripts: []' instead of a traceback.

Applied inline mktemp guards across all mktemp calls in widget-create.sh, validate.sh, fetch-secret.sh, and auth-probe.sh. On failure the scripts emit structured error JSON matching the existing contract and clean up any earlier tempfiles before exit. - fetch-secret.sh accessed errors[0] without first checking that errors is a list. Added isinstance(errors, list) guard and applied the same fix to widget-create.sh, validate.sh, and auth-probe.sh which have the same pattern. - persist-skill.sh had a python3 command -v guard but not one for npx (needed for the degit call).

Fixes applied to SKILL.md, all six framework references, the four helper scripts, the test doc, and the README: - Run every embedded python3 invocation with -I to prevent cwd-relative module shadowing of stdlib (urllib, json, hashlib, os, re, sys). Covers -c inline, - stdin heredoc, and the bootstrap loop. - auth-probe.sh: distinguish network_failure and upstream_failure from missing_scope; SKILL.md Step 3 documents branches for both. - SKILL.md Step 3: post-auth recovery resumes at Step 4 (the numbered wizard) instead of jumping over Steps 4-7. - SKILL.md Step 9: require git check-ignore before writing to any .env-style file, with fallback to the platform's secret manager. - Framework references (vanilla-html, nextjs-app, nextjs-pages, astro, sveltekit, hugo): inline a TURNSTILE_HOSTNAMES allowlist and compare result.hostname against it in every server-side snippet. Includes Node, Ruby, and Python variants in vanilla-html. - README: recommend the git-clone/symlink install path; keep the single-file curl bootstrap only as a read-only fallback with a note that persist-skill.sh needs the cloned bundle. - Remove fetch-secret.sh (superseded by the in-flow existing-widget recovery in SKILL.md, no callers remain). Scripts still pass shellcheck and safe smoke tests (missing_token, file_target_not_supported, empty-array rejection, unsupported-mode rejection).
