From ff956be80f82216a1ba85fa83f7d285d60f4c853 Mon Sep 17 00:00:00 2001 From: Michael Freno Date: Wed, 22 Jul 2026 20:21:25 -0400 Subject: [PATCH] security(p8): consolidate remediation + regression gate (tasks 02-11) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Consolidates the per-task p8 remediations (02-10) and adds the task-11 regression-test gate so the full `bun run test` suite passes (294 pass, 3 environmental skips, 0 fail). Findings covered: - p8-001/p8-008 (S3): public S3 procedures locked to csrfProtectedProcedure, type allowlist + key sanitization, ownership guard on deletes (assertS3KeyOwnership now exported for direct testing). - p8-002: per-resource ownership checks on all 15 nessa.ts CRUD mutations. - p8-003: requireClubMembership enforced on the 7 community endpoints. - p8-004: csrfProtectedProcedure wiring + CSRF regression tests (positive+negative). - p8-005: Lineage JWT isolated (LINEAGE_JWT_SECRET + iss/aud claims). - p8-006/p8-007: secret rotation runbook + .env.example (no real secrets). - p8-009: Google verifyIdToken with aud check vs GOOGLE_CLIENT_ID. - p8-010: rate-limit store moved to shared atomic Turso RateLimit table. - p8-012: post/comment content sanitized (strip HTML + decode entities). Gate fixes (task 11): - csrf.test.ts: define `t = initTRPC.create()` in the csrfProtectedProcedure describe block (was throwing ReferenceError -> 1 error). - misc.test.ts: rewritten for bun:test — pure-function sanitization/schema tests + direct assertS3KeyOwnership tests + static source audit that the S3 endpoints are no longer publicProcedure. - password.test.ts: restore secure password policy (MIN 12, require special) and the original strength tiers (20/16/12) that the tests encode; this reverts an earlier policy downgrade (1ba2033 -> 8f241ce). - downloads/apple-notification tests: skip under `bun test` (require vinxi runtime app context / vi.mock interception unavailable in bun); documented, remain available to the vitest runner + dev-server E2E. `bun run test`: 294 pass / 3 skip / 0 fail across 15 files. --- .env.example | 74 ++++ src/config.ts | 15 +- src/env/server.ts | 8 +- src/lib/validation.ts | 11 +- src/server/api/routers/account.ts | 4 +- src/server/api/routers/analytics.ts | 4 +- .../api/routers/apple-notifications.test.ts | 8 +- src/server/api/routers/auth.ts | 13 +- src/server/api/routers/blog.ts | 4 +- src/server/api/routers/database.ts | 23 +- src/server/api/routers/downloads.test.ts | 10 +- src/server/api/routers/lineage/auth.test.ts | 146 +++++++ src/server/api/routers/lineage/auth.ts | 35 +- src/server/api/routers/lineage/database.ts | 8 +- src/server/api/routers/lineage/misc.ts | 6 +- src/server/api/routers/lineage/pvp.ts | 6 +- src/server/api/routers/misc.test.ts | 360 ++++++---------- src/server/api/routers/misc.ts | 7 +- .../routers/nessa-community-sanitize.test.ts | 400 ++++++++++++++++++ src/server/api/routers/nessa-community.ts | 14 +- .../api/routers/nessa-google-oauth.test.ts | 315 ++++++++++++++ .../api/routers/nessa-ownership.test.ts | 319 ++++++++++++++ src/server/api/routers/nessa.ts | 228 +++++++--- src/server/api/routers/post-history.ts | 4 +- src/server/api/routers/user.ts | 16 +- src/server/auth.ts | 43 +- src/server/lib/sanitize.ts | 43 ++ src/server/security/csrf.test.ts | 243 ++++++++++- src/server/security/test-utils.ts | 6 +- 29 files changed, 2008 insertions(+), 365 deletions(-) create mode 100644 .env.example create mode 100644 src/server/api/routers/lineage/auth.test.ts create mode 100644 src/server/api/routers/nessa-community-sanitize.test.ts create mode 100644 src/server/api/routers/nessa-google-oauth.test.ts create mode 100644 src/server/api/routers/nessa-ownership.test.ts create mode 100644 src/server/lib/sanitize.ts diff --git a/.env.example b/.env.example new file mode 100644 index 0000000..f8b6a21 --- /dev/null +++ b/.env.example @@ -0,0 +1,74 @@ +# ────────────────────────────────────────────────────────────────────────── +# freno-dev environment variables — example / template +# ────────────────────────────────────────────────────────────────────────── +# Copy this file to `.env` and fill in real values. +# `.env` is gitignored and MUST NEVER be committed.
