From a20f2ef94d8664b5bc8a4d3083222bc3c38b16d5 Mon Sep 17 00:00:00 2001 From: woahwhattheheck Date: Thu, 24 Sep 2026 15:49:39 -0400 Subject: [PATCH 1/8] Keep client PII off public pay, verify, proof, and log surfaces Closes #559. PUBLIC_INVOICE_FIELDS is the single allowlist for anonymous pay, payment-info, and verify. SELLER_ONLY_INVOICE_FIELDS names the identity keys that must stay off those responses, proof HTML, mailto bodies, payment-event payloads, and structured logs. Seller workspace reads gated by the invoice Freighter wallet still return client contact. Pay-page types drop the index signature and seller-only fields so a leaked key fails the frontend typecheck. Named whitelist tests fail if a public key is removed or a seller-only key is dropped from the denylist. --- backend/src/utils/payment-event-redaction.ts | 7 +- backend/tests/invoice-handlers.test.ts | 15 +- backend/tests/log-events.test.ts | 25 ++++ .../tests/public-invoice-whitelist.test.ts | 130 ++++++++++++++++++ docs/QUITTANCE_PROOF_SPEC.md | 6 +- frontend/components/PayAmountBlock.tsx | 8 -- frontend/components/PayProofPanel.tsx | 23 +++- frontend/components/PaymentReceipt.tsx | 63 +-------- frontend/components/pay-page.types.ts | 39 ++---- frontend/lib/export.ts | 21 +-- frontend/lib/mailto-delivery.js | 6 - frontend/lib/payment-page-state.d.ts | 6 +- frontend/tests/mailto-delivery.test.js | 30 +++- frontend/tests/pay-page-public-dto.test.js | 96 +++++++++++++ shared/invoice.ts | 53 +++++++ 15 files changed, 390 insertions(+), 138 deletions(-) create mode 100644 backend/tests/public-invoice-whitelist.test.ts create mode 100644 frontend/tests/pay-page-public-dto.test.js diff --git a/backend/src/utils/payment-event-redaction.ts b/backend/src/utils/payment-event-redaction.ts index 0c1bf95f..4d303b0f 100644 --- a/backend/src/utils/payment-event-redaction.ts +++ b/backend/src/utils/payment-event-redaction.ts @@ -5,9 +5,12 @@ * keys before rows leave the server so the audit read can never become a PII * side channel.

Sign one session-scoped message per wallet instead: the backend honours a session signature on any seller read for up to an hour while route-scoped signatures keep their existing 60-second binding. Adds SELLER_SESSION_SCOPE / SELLER_SESSION_MAX_AGE_MS to the shared proof contract and handler-level coverage for cross-scope session acceptance, a stale session proof, an expired session and a foreign-wallet signature.
