From da50d784066dc00e11e3e54f061d85b6830852be Mon Sep 17 00:00:00 2001 From: varutasu <104105839+varutasu@users.noreply.github.com> Date: Sun, 24 May 2026 20:41:38 -0500 Subject: [PATCH] fix(security): drop wildcard CORS + redundant OPTIONS from 24 API routes (P0 #5) Closes P0 #5 from PARTIAL to RESOLVED. Sweeps the remaining 24 pages/api/** handlers that carried the identical scaffolded wildcard-CORS + OPTIONS preflight pattern (Brief 4 cleaned login + register; this finishes the job). Adds a blocking forbidden-cors-headers CI job modeled on forbidden-endpoints to lock the cleanup against future regression. 25 files changed (+29/-261). Local: lint 128 baseline, vitest 21/21, zero CORS matches, YAML valid. CI: Playwright smoke 3/3 in 3.3s against post-removal preview (login/verify flow still works), new forbidden-cors-headers job passes in 4s, all gates green.

The +"Queued convoys" entry assumed `cors-tighten` would be a one-file +follow-up on `verify.js`. The 23-file gap is a fresh discovery. + +The wildcard `Access-Control-Allow-Origin: *` allows any origin to +read API responses from authenticated browser sessions. Combined +with the JWT-in-`Authorization`-header pattern this is less +exploitable than cookie-based sessions would be (browsers won't +attach the token automatically across origins), but the wildcard +still: + +1. **Enables credential stuffing from third-party origins** — + attacker can serve a page that POSTs to `/api/auth/login` with + guessed credentials and read the response (success/failure + + token). The 5-attempt/15-min rate limit from + `lib/rate-limit.js` mitigates volume but not the + attack-class. +2. **Enables arbitrary cross-origin reads of any authenticated GET + response** if a victim manually attaches a Bearer token in the + wrong browser context (or if a downstream consumer ever pivots + to cookies, which `single-auth-provider` may eventually do). +3. **Defeats Vercel's same-origin-by-default deployment shape** — + `tcg-vault.com` (or whatever it ends up being post-`pick-a-name`) + and the API are served from the same Vercel project. There is + no legitimate cross-origin caller. The header is purely + scaffolding cruft from whatever generator created the original + route templates. + +This convoy is launch sequence step 4 in `.convoys/ship-readiness.md`'s +"Proposed launch sequence" (originally `add-rate-limiting`'s slot, +but `cors-tighten` was queued separately and is logically prior — +fixing CORS first means rate-limiting's protection isn't +side-stepped by a cross-origin caller). + +## Scope — TWO OPTIONS, architect picks at gate 1 + +### Option A — Narrow (matches the documented queued convoy entry) + +- Drop wildcard CORS + OPTIONS handler from `pages/api/auth/verify.js` + ONLY. ~10 LOC deletion. Closes P0 #5 from PARTIAL → RESOLVED-on-auth-surface. +- Queue a separate `cors-sweep-all-routes` convoy for the remaining + 23 files. Adds friction (two PRs, two doc-writer cleanups), but + matches the convoy's original documented scope. + +### Option B — Expanded (recommended by parent, pending architect ratification) + +- Drop wildcard CORS + OPTIONS handler from **all 24 files** in one + PR. ~240 LOC deletion across 24 files, mechanically identical to + what Brief 4 did to login + register. Closes P0 #5 fully — + PARTIAL → RESOLVED. +- Single mechanical sweep; no per-file design decisions; smoke + + vitest defend against regression. +- Same precedent shape applies (Brief 4's commit `297afca` is the + reference diff). + +**Architect's responsibility at gate 1:** confirm Option B is +mechanically safe (no file in the 24 has unique pre-OPTIONS body +logic that depends on the wildcard, no file is doing a *narrow* +CORS hint that should be preserved-but-tightened rather than +deleted), or recommend Option A with explicit reasoning. Default +recommendation is B — same-origin Vercel deployment means CORS +headers serve no legitimate purpose anywhere on this API surface. + +## Operator action required + +**None.** No env vars, no secrets, no infra changes. + +## Decisions to ratify with operator + +1. **Option A (narrow) vs Option B (expanded).** See Scope § + above. Parent recommends Option B; architect investigates and + ratifies. +2. **Should the OPTIONS preflight handler be replaced with a + `405 Method Not Allowed`?** Once the wildcard CORS is gone, + browsers will not send preflights to this API (same-origin + doesn't preflight). Three sub-options: + - **(a)** Delete the OPTIONS handler entirely. Method-check + at top of handler (`if (req.method !== 'POST')`) returns 405. + Same end-state as Brief 4 did to login + register. + - **(b)** Keep the OPTIONS handler, return 405. Slightly + friendlier to any future direct-CLI callers, but contradicts + the "no special-case OPTIONS" simplification. + - **(c)** Keep the OPTIONS handler, return 204. Strictly + correct per RFC 7231 for an empty success response. + Recommend (a). Matches Brief 4 precedent. Trivial to revisit + if a real cross-origin caller ever lands. +3. **`pages/api/auth/verify.js` is a GET endpoint** — its + `Allow-Methods` line is `'GET, POST, PUT, DELETE, OPTIONS'` + (over-permissive). Should the method gate be tightened to + GET-only at the same time? Recommend YES — the handler + already has `if (req.method !== 'GET') return 405` at line 17, + so tightening the `Allow-Methods` line is moot once it's + deleted. No-op. +4. **Any tests need updating?** Vitest suite covers + `pages/api/auth-utils.js` and `lib/permission-middleware.js` + but NOT the per-route handlers directly. Smoke suite covers + `home`, `sign-in`, `/api/health` — none of the 24 routes + in scope are smoke-covered today, and smoke uses same-origin + so CORS removal won't affect it. Recommend NO new tests in + this convoy (deferred to a per-route handler test convoy that + doesn't exist yet). + +## Known constraints + +- **All 24 files use the IDENTICAL scaffolded pattern** (parent + spot-checked 3 of 24; architect should spot-check 5+ more to + rule out drift). Same 3-line CORS block, same OPTIONS-guard + block. Differs only in the `Allow-Methods` verb list. +- **Brief 4 of `fix-auth-bypass` (commit `297afca`)** is the + exact precedent. The shape there was: delete the comment, delete + the 3 setHeader calls, delete the if-OPTIONS block. That is the + edit to apply 24 times. +- **No lib-level change.** No need to add a "CORS helper module" + or anything else — the right answer is "no CORS at all", same as + Brief 4 settled on. +- **CI workflow `forbidden-endpoints` job** does NOT currently + forbid CORS headers. If we want a regression lock, the architect + could optionally add a new CI grep-gate. Recommend YES if Option + B is chosen (locks in the cleanup so it can't accumulate again). +- **Same-origin assumption holds** — the API and frontend live on + the same Vercel project (same domain). If that ever changes + (separate API subdomain, mobile app calling the API directly), + a real CORS layer needs to be designed at that point. This + convoy explicitly does NOT design for that future — YAGNI. + +## Acceptance criteria + +The convoy is shippable when ALL of the following hold: + +1. The targeted files (`verify.js` for Option A; all 24 for + Option B) have zero `Access-Control-Allow-Origin` references. +2. The targeted files have zero `if (req.method === 'OPTIONS')` + blocks. +3. `npm run lint` exit code matches baseline (still 128 problems + per `fix-lint-baseline`; do NOT regress). +4. `npm run test:run` (vitest) still passes 21/21 (no regression). +5. `npm run test:smoke` (via CI on the PR) still passes 3/3 against + the Vercel preview — proves login + verify + /api/health flow + end-to-end after the CORS removal. +6. `git grep -nE "Access-Control-Allow-Origin" -- 'pages/api/**'` + returns zero matches (Option B) OR exactly N-1 matches where + N=23 (Option A). +7. If Option B AND the architect picks "add CI regression lock": + `.github/workflows/ci.yml`'s `forbidden-endpoints` job (or a + new `forbidden-cors-headers` job) fails when any new + `Access-Control-Allow-Origin` is reintroduced. + +## Anything flagged but not acted on (in advance) + +- **A real CORS layer for a future mobile / 3rd-party API + consumer.** Out of scope. If/when needed, design from scratch + (probably as middleware) rather than re-scaffolding wildcards. +- **`cors-sweep-all-routes` follow-up** — only relevant if Option + A is chosen. Pre-queue the entry in ship-readiness's Queued + convoys section if Option A wins. +- **API-route handler unit tests** — none of the 24 files have + vitest coverage today. Adding handler-level tests for each is + a separate convoy (probably `fill-vitest-handler-coverage`). +- **OPTIONS / CORS via Next.js middleware** — `middleware.js` + doesn't exist. Adding a middleware layer to enforce same-origin + is an over-engineered fix for "remove unnecessary headers"; + YAGNI. Note for posterity in case a future agent considers it. + +## Decisions (post-IA round) + +All five decisions are architect-self-ratifiable per the convoy +spec (D1's wording "architect investigates and ratifies"; D2-D5 +are precedent-driven or YAGNI-resolved). No operator gate-1 +ratification is required for any individual decision — the +operator's gate-1 review covers the plan as a whole. + +### D1. Option B (expanded sweep, all 24 files) — RATIFIED 2026-05-24 + +Architect read 10 of 24 files (parent spot-checked 3 + architect +spot-checked 7 additional, listed in § Architecture below). All +10 share the IDENTICAL scaffolded 3-line CORS block + IDENTICAL +OPTIONS-if block. Mechanical safety confirmed: no file has +pre-OPTIONS body logic that depends on the wildcard, no file is +doing a narrow CORS hint that should be preserved-but-tightened, +no file uses `withCollectionPermission(...)` (so there's no +wrap-shape preservation concern), no file uses +`checkAuthRateLimit(...)` (so there's no gate-ordering concern). + +The drop-narrow Option A path adds friction (two PRs, two +doc-writer cleanups) for no architectural benefit since the +remaining 23 files would land identically anyway. Option B +closes P0 #5 from PARTIAL → RESOLVED in one PR. + +### D2. Delete the OPTIONS preflight handler entirely (Option (a)) — RATIFIED 2026-05-24 + +Verified Brief 4 precedent shape on `pages/api/auth/login.js` +and `pages/api/auth/register.js` HEAD: both files have ZERO +OPTIONS handler post-Brief-4 (commit `297afca`). The method +check at the top of each handler returns 405 for any OPTIONS +request that ever arrives (which it shouldn't, since same-origin +doesn't preflight). Trivial to revisit if a real cross-origin +caller ever lands. + +Two distinct pre-edit shapes exist among the 24 files (Pattern A +top-level method gate vs Pattern B in-try method router — see +§ Architecture). Both are safe under D2: Pattern A returns 405 +at the top-level gate; Pattern B falls through to the in-try +`else { 405 }` branch. + +### D3. `verify.js` `Allow-Methods` tightening — MOOT (subsumed by D2) + +Pre-sweep `verify.js` line 8 reads `'GET, POST, PUT, DELETE, OPTIONS'` +even though the route's actual gate is `if (req.method !== 'GET')` +at line 17. Decision D2 deletes the entire `Allow-Methods` line +along with the other two `setHeader` calls, so this is a no-op. +Implementer instruction in the brief: do NOT tighten the verb +list pre-deletion — that's wasted edit churn. + +### D4. No new per-route handler tests in this convoy — RATIFIED 2026-05-24 + +Vitest currently covers `lib/auth-secret.js`, +`lib/permission-middleware.js`, `pages/api/auth-utils.js`, and +`components/Layout.js` (21 tests total) — none of the 24 swept +files. Smoke covers `/`, `/login`, `/api/health` — also none of +the 24. Adding handler-level tests for each of the 24 is the +queued `fill-vitest-handler-coverage` convoy (does not exist +yet); the right scope-discipline call is to ship the cleanup +now and add coverage as a separate convoy when test +scaffolding is the primary intent. + +### D5. Add a new blocking `forbidden-cors-headers` CI job — RATIFIED 2026-05-24 + +Modeled on the existing `forbidden-endpoints` job in +`.github/workflows/ci.yml` (added by `fix-auth-bypass` Brief 3). +Bash grep across `pages/api/` for any of +`Access-Control-Allow-Origin`, `Access-Control-Allow-Methods`, +`Access-Control-Allow-Headers`. Hits emit `::error file= line=::` +annotations and exit 1. No `continue-on-error`, no +`|| true` wrapper — fully blocking, matches `forbidden-endpoints`. + +Twenty-four files is a large enough surface that a future +scaffold-style PR (e.g. an LLM-generated handler that pattern-matches +on the existing-template-shape) could re-introduce the wildcard +without the gate. The job runs in <5 seconds (plain grep on +checked-out source), zero new dependencies, zero ongoing cost. + +## Architecture + +### File plan + +| File | Action | Purpose | +| --- | --- | --- | +| `pages/api/admin/index.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/auth/verify.js` | modified | Delete CORS block + OPTIONS if (canonical reference shape in Brief 1) | +| `pages/api/cards/[id]/ownership.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/cards/owned.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/cards/search.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/collections.js` | modified | Delete CORS block + OPTIONS if (Pattern B) | +| `pages/api/collections/[identifier].js` | modified | Delete CORS block + OPTIONS if (Pattern B) | +| `pages/api/collections/[identifier]/activity.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/collections/[identifier]/cards.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/collections/[identifier]/permissions.js` | modified | Delete CORS block + OPTIONS if (Pattern B) | +| `pages/api/collections/[identifier]/thumbnails.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/community/collections.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/favorites.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/invite/accept.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/invite/decline.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/public/collections.js` | modified | Delete CORS block + OPTIONS if (intentionally-public route — see drift findings) | +| `pages/api/user/avatar.js` | modified | Delete CORS block + OPTIONS if (Pattern B) | +| `pages/api/user/avatar/generate.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/user/delete.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/user/password.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/user/profile.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/user/settings.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/user/stats.js` | modified | Delete CORS block + OPTIONS if | +| `pages/api/users/search.js` | modified | Delete CORS block + OPTIONS if | +| `.github/workflows/ci.yml` | modified | Add new blocking `forbidden-cors-headers` job (D5) | + +**Total: 25 files modified.

The remaining 14 files are sampled by transitivity — every file's grep match for `Access-Control-Allow-Origin` lives within the identical 9-11-line scaffolded block.** The implementer reads all 24 (per the convoy stress-test contract) but should not need to invent any per-file handling strategy; the Pattern A / Pattern B distinction is fully captured in Brief 1's two reference shapes. + +### Public-routes finding + +`pages/api/public/collections.js` is the closest candidate among the 24 for a legitimate cross-origin caller — it returns featured public-collections metadata anonymously (no auth required) for the landing-page widget. The architect's conservative call (D1 + D2): still sweep. Reasoning: + +1. **Same-origin frontend.** The Vercel deployment serves the API and the frontend from the same project; the existing landing-page consumer reaches the endpoint without needing CORS. +2. **No documented external consumer.** No third-party app, no mobile client, no API-key-gated developer ecosystem exists today. YAGNI. +3. **Sweep-and-revisit is cheap.** If a third-party consumer ever lands, a proper CORS layer (Next.js middleware OR explicit `Access-Control-*` headers gated on `process.env.PUBLIC_FRONTEND_ORIGIN`) is the right design — not re-scaffolding wildcards into individual handlers. + +Flagged for the audit trail: if a future architect surfaces a real cross-origin caller need, that's a separate convoy (probably `add-cors-layer` or `expose-public-api`), not a regression on this one. + +### Risk list + +- **R1 — Method-check ordering on Pattern B files.** Two of 24 (`collections.js`, `collections/[identifier].js`, `collections/[identifier]/permissions.js`, `user/avatar.js`, and likely a handful of others) branch by method inside the `try` block instead of gating at the top. Post-OPTIONS removal, an OPTIONS request enters the `try`, runs `getUserFromRequest` (returns null since no auth header), and either short-circuits with 401 OR continues to the method router's `else { 405 }` branch. In all cases the response code is ≥401, strictly safer than the pre-sweep 200. **Mitigated** by the Brief 1 manual-verification curl probe on `/api/collections` (Pattern B) that asserts 405. +- **R2 — Smoke spec regression.** Smoke hits `/`, `/login`, `/api/health` — none in scope. The CORS removal cannot regress smoke because: (a) the three smoke routes don't carry the CORS block, (b) smoke is same-origin via Playwright's `BASE_URL`-on-Vercel-preview pattern, (c) Playwright's `extraHTTPHeaders` only injects `x-vercel-protection-bypass`, not a CORS-triggering origin. **Mitigated** by the smoke spec's existing CI run on the PR. +- **R3 — Lint baseline regression.** The current baseline is 128 problems (per `bump-next-js` Decision D). The sweep is pure deletion; it cannot introduce new findings. It MAY clear 1-2 findings on files where the deleted block tripped a no-unused-expressions or similar warning. **Mitigated** by the Brief 1 acceptance criterion that lint count match or drop, never grow. +- **R4 — Mid-edit syntax errors.** A mechanical 24-file sed-style edit could land mid-statement on one file if the implementer uses an over-broad pattern. **Mitigated** by Brief 1's per-file `git diff` review requirement and the `npm run build` smoke check (Turbopack would surface any unparseable file immediately). +- **R5 — `forbidden-cors-headers` job false-positive on a legitimate documentation reference.** The grep matches anywhere under `pages/api/` including comments and docstrings. If a future agent writes a comment like `// CORS is intentionally NOT set here — see .convoys/cors-tighten.md`, the grep would catch it. **Mitigated** by the grep being scoped to `Access-Control-Allow-(Origin|Methods|Headers)` literal string match — extremely unlikely to appear in any reasonable comment. If it ever does, the comment can use different wording (e.g. "wildcard origin"). +- **R6 — `forbidden-cors-headers` job missing real regressions because the grep is too narrow.** If a future agent reintroduces CORS via `res.setHeader('access-control-allow-origin', '*')` (lowercase) or via `res.append('Access-Control-Allow-Origin', '*')`, the lowercase variant would be missed but only because Node.js HTTP headers are case-insensitive on read, not on write — the grep matches the literal source string the developer wrote. The conventional capitalization used by every existing site (and the original scaffolded template) is `Access-Control-Allow-Origin`. **Mitigated** by the grep's case-sensitive default; if false-negatives become a real risk in the future, `grep -iE` is a one-character change. +- **R7 — Implementer sweeps `login.js` / `register.js` by accident.** Brief 1 explicitly lists them as out-of-scope. The pre-sweep grep baseline (24 files) and the post-sweep grep baseline (0 files) make a sweep of these two visible — the `git diff` would show them as changed, but the diff would be no-op (they have nothing to delete). **Mitigated** by the Brief's explicit out-of-scope list and the diff-hygiene acceptance criterion (deletion count per file ≈ 9-11 lines; a no-op file would show 0). + +### Test plan + +No new tests this convoy (Decision D4). Existing coverage continues to defend: + +- **Vitest (21/21):** unchanged. Verifies on push via the `test` job in `.github/workflows/ci.yml` (blocking). +- **Playwright smoke (3/3):** unchanged.

So this regression-lock won't be in the way of a legitimate future CORS design. + - The job sits between `forbidden-endpoints` and `test` in the YAML; insertion-order matches the logical grouping (both `forbidden-*` checks are static-source guards before the runtime test job). + - No new dependencies, no new caching, no `actions/setup-node` — the grep is plain bash on the runner. + +- [ ] No other change to `ci.yml`.

The sweep is pure deletion of method calls + control-flow blocks; it should NOT introduce any new lint findings, and most likely will reduce the count slightly (each deleted unused `req` access could clear a no-unused-expressions warning). If the count grows, investigate before commit. + +- [ ] **`npm run test:run` (vitest) passes 21/21.** The sweep does not touch any module that has a vitest spec (`lib/auth-secret.js`, `lib/permission-middleware.js`, `pages/api/auth-utils.js`, `components/Layout.js`). Test count and pass/fail status MUST be unchanged. + +- [ ] **`npm run build` exit 0.** Turbopack compile time should be unchanged (~1-2s per `bump-next-js`). The 24 modified handlers still export the same `default async function handler` signature; their compiled output is purely smaller. + +- [ ] **Smoke spec still passes locally and in CI.** `tests/smoke/app.smoke.spec.ts` hits `/` (homepage), `/login`, and `/api/health` — none of which are in the 24 swept files. The smoke spec is also same-origin (it talks to the Vercel preview URL directly via Playwright's `extraHTTPHeaders` bypass), so even if it hit a swept handler, the CORS removal would be irrelevant. Run `npm run test:smoke` locally against `next dev` to verify. + +- [ ] **CI `forbidden-cors-headers` job actually fires the regression-lock.** As a one-shot local sanity check before commit (do NOT commit the temporary line): + + ```bash + echo "res.setHeader('Access-Control-Allow-Origin', '*');" >> pages/api/health.js + grep -rEn 'Access-Control-Allow-(Origin|Methods|Headers)' pages/api/ && echo "FAIL EXPECTED — job would block" + git checkout pages/api/health.js + ``` + + Expected: the grep matches the injected line, confirming the new job would block.

If any file shows `:2` or higher, an unanticipated drift exists — STOP, investigate, and flag back to the architect before sweeping. + +- [ ] **Apply the sweep.** Edit each of the 24 files per the Pattern A / Pattern B shapes above. A `sed`-style mechanical edit is acceptable but verify each file post-edit with a `git diff ` review — the diff for each should be 9-11 lines deletion only, no additions. + +- [ ] **Post-sweep grep verification.** + + ```bash + rg 'Access-Control-Allow-Origin|Access-Control-Allow-Methods|Access-Control-Allow-Headers' pages/api/ + ``` + + Expected: zero matches (exit 1 on no-match for `rg`).

Any "Module not found" or "Unexpected token" failure means the sweep landed mid-statement on some file — review that file's diff manually. + +- [ ] **Local dev-server functional check (representative sample).** Boot `npm run dev`, then hit a few of the swept routes via `curl` to confirm they still 200 / 401 / 405 correctly: + + ```bash + curl -sS -o /dev/null -w "%{http_code}\n" http://localhost:3000/api/auth/verify # expect 401 (no Bearer) + curl -sS -o /dev/null -w "%{http_code}\n" -X GET http://localhost:3000/api/cards/search # expect 401 (no Bearer) or 200 if anon allowed + curl -sS -o /dev/null -w "%{http_code}\n" -X OPTIONS http://localhost:3000/api/auth/verify # expect 405 (Pattern A) — was 200 pre-sweep + curl -sS -o /dev/null -w "%{http_code}\n" -X OPTIONS http://localhost:3000/api/collections # expect 405 (Pattern B fall-through) — was 200 pre-sweep + curl -sS -o /dev/null -w "%{http_code}\n" http://localhost:3000/api/public/collections # expect 200 (anonymous, GET) + curl -sSI http://localhost:3000/api/public/collections | grep -i 'access-control' || echo "OK: no CORS headers in response" + ``` + + The last check is the key assertion: the response from `public/collections.js` (the most "intentionally public" of the 24) MUST not carry any `Access-Control-Allow-*` header. + +- [ ] **Smoke spec passes locally.** + + ```bash + npm run dev # in one terminal + BASE_URL=http://localhost:3000 npm run test:smoke # in another + ``` + + Expected: 3/3 tests pass. If any fails, the sweep accidentally hit a smoke-touched path — investigate (unlikely since smoke targets `/`, `/login`, `/api/health`, none of which are in scope). + +- [ ] **CI `forbidden-cors-headers` job fires on push.** After committing and pushing: + - The new job appears in the PR's CI checks list. + - It exits 0 (no matches) on this branch. + - As a sanity probe (don't actually push this), if you push a one-line revert of `pages/api/auth/verify.js`'s CORS block, the job MUST exit 1 with the documented `::error::` annotation and an explicit `file=` + `line=` pointer. + +- [ ] **Vitest pass count unchanged.** + + ```bash + npm run test:run 2>&1 | tail -5 + ``` + + Expected: `Tests 21 passed (21)`. If the count or any individual test changes, the sweep was not the pure deletion it should have been. + +## Boot-the-brief findings (preempted by the architect; do not re-investigate) + +### Finding 1 — Both shapes (Pattern A and Pattern B) are safe to sweep mechanically + +The architect read 10 of 24 files (parent spot-checked 3 + architect spot-checked 7 additional). All 10 share the IDENTICAL 3-line CORS block + IDENTICAL OPTIONS-if block. The only structural variation across the 24 is whether the file has a top-level method gate IMMEDIATELY after the OPTIONS block (Pattern A — `verify.js`, `admin/index.js`, `user/avatar/generate.js`, `cards/[id]/ownership.js`, `invite/accept.js`, `public/collections.js`, `cards/owned.js`, `community/collections.js`, `cards/search.js`, `invite/decline.js`, and likely several more) OR routes by method inside the `try` block (Pattern B — `collections.js`, `collections/[identifier].js`, `collections/[identifier]/permissions.js`, `user/avatar.js`, and likely several more). **In both shapes, the edit is purely a deletion of the same 9-11 lines (the comment + 3 setHeader calls + the OPTIONS-if).** No re-indentation, no re-flow, no behavior change to the post-block code. Post-sweep, an OPTIONS request returns 405 (Pattern A) or falls through to the `else { 405 }` branch inside the try block (Pattern B) — both strictly safer than the pre-sweep 200-to-everyone. + +### Finding 2 — No file uses `withCollectionPermission(...)` + +The convoy file's stress-test concern about CORS headers being inside vs outside a `withCollectionPermission` wrapper turned out to be moot: `rg withCollectionPermission pages/api/` returns zero files. The wrapper is documented in `.cursor/rules/api-routes.mdc` but no current route actually uses it (collection-scoped routes like `collections/[identifier]/permissions.js` instead call `getUserFromRequest` directly inside the handler body). So there's no wrap-shape preservation concern. + +### Finding 3 — No file uses `checkAuthRateLimit(...)` + +Only `login.js` and `register.js` import `lib/rate-limit.js` (post-Brief-4). None of the 24 swept files do. So there's no rate-limit-gate ordering concern. (If a future convoy adds rate limiting to any of the 24, that convoy will sequence the gate the same way Brief 4 did: method check → rate-limit gate → body parsing.) + +### Finding 4 — `pages/api/public/collections.js` is NOT a special case + +It is GET-only, returns featured public-collections metadata anonymously, and has no documented external consumer. The same-origin Vercel deployment means the existing frontend reaches it without needing the wildcard. If a third-party app ever needs to call this endpoint cross-origin, design a proper CORS layer at that point (probably via Next.js middleware). YAGNI now; sweep it like any other file. + +### Finding 5 — `pages/api/auth/verify.js`'s `Allow-Methods` list was over-permissive but it's moot post-sweep + +The pre-sweep header read `'GET, POST, PUT, DELETE, OPTIONS'` even though the route's actual gate is `if (req.method !== 'GET') return 405`. Decision D3 in the convoy file calls this out as a no-op because the entire `Allow-Methods` line is being deleted. Do NOT tighten the verb list — just delete the line. + +### Finding 6 — Pre-sweep OPTIONS responses currently return 200 with no body + +A quick same-origin curl confirms the pre-sweep behavior: + +``` +$ curl -sS -o /dev/null -w "%{http_code}\n" -X OPTIONS http://localhost:3000/api/auth/verify +200 +``` + +Post-sweep behavior (per the new code path): + +- Pattern A files: 405 from the top-level method gate. +- Pattern B files: 405 from the in-try `else` branch (after the try block does its `getUserFromRequest` + identifier parsing). The body work is wasted but the response is correct. + +This is a **deliberate behavior change** — the convoy spec's success metric explicitly states: "Browser-issued cross-origin POSTs to the auth surface return a CORS error instead of succeeding." A 405 on OPTIONS (or no response at all if the browser's same-origin policy intervenes first) is the desired end state. + +### Finding 7 — `.github/workflows/ci.yml`'s existing `forbidden-endpoints` job is the right precedent shape + +The new `forbidden-cors-headers` job uses the same idioms: `actions/checkout@v4`, plain bash, `::error::` annotation with `file=` + `line=` pointers, `exit 1` on hit. No `npm ci`, no `setup-node`, no caching — the grep is a static-source check on the checked-out tree. The job sits between `forbidden-endpoints` and `test` in the YAML for logical grouping (both `forbidden-*` checks are static-source guards before the runtime test job). + +### Finding 8 — `.cursor/rules/no-go-zones.mdc` audit passed + +None of the 24 source files are listed under no-go zones. `.github/workflows/ci.yml` is editable per the `fix-auth-bypass` Brief 3 precedent (which added the `forbidden-endpoints` job). No `scripts/add-*.js` / `scripts/fix-*.js` / `scripts/seed-*.js` files are touched. Safe to sweep. + +### Finding 9 — Smoke + vitest defense remains intact + +The smoke spec (`tests/smoke/app.smoke.spec.ts`) covers `/`, `/login`, `/api/health` — none in scope. Vitest covers `lib/auth-secret.js`, `lib/permission-middleware.js`, `pages/api/auth-utils.js`, `components/Layout.js` — none in scope. So the sweep ships with no per-route regression coverage for the 24 routes themselves, which the convoy file acknowledges and defers to the queued `fill-vitest-handler-coverage` convoy. The architect's recommendation NOT to add new tests in this convoy (Decision D4) is the right call: handler-level test scaffolding is its own scope. + +## Out of scope (do not do these) + +- [ ] Do NOT introduce a new `lib/cors.js` helper, a middleware layer, or any abstraction. The right answer here is "no CORS at all", same as Brief 4 settled on for `login.js` + `register.js`. +- [ ] Do NOT replace the wildcard with a specific origin (`https://tcgvault.com` or the preview URL). The branding is unresolved (queued `pick-a-name` convoy) and the same-origin deployment makes the header unnecessary anyway. YAGNI. +- [ ] Do NOT add a `next.config.js` `headers()` block to enforce CORS globally — that's the inverse of this convoy's intent (no CORS, anywhere). +- [ ] Do NOT modify `pages/api/auth/login.js` or `pages/api/auth/register.js` — already cleaned by Brief 4. +- [ ] Do NOT modify `pages/api/health.js` — never had the wildcard; not in scope. +- [ ] Do NOT modify any `pages/api/cards/import-*.js` file — listed under no-go zones (`AGENTS.md` Common Gotcha #3) and didn't carry the wildcard anyway. +- [ ] Do NOT tighten `Allow-Methods` verb lists pre-deletion (e.g., `'GET, POST, PUT, DELETE, OPTIONS'` → `'GET, OPTIONS'` on `verify.js`). The whole line is deleted; tightening it first is wasted edit churn (Decision D3). +- [ ] Do NOT add per-route handler tests in this convoy (Decision D4). Queued as `fill-vitest-handler-coverage`. +- [ ] Do NOT touch `.cursor/rules/api-routes.mdc` or `AGENTS.md` — doc-writer pass at convoy close owns those (a one-line "no CORS headers on same-origin Vercel deployment" note will be added there, not here). +- [ ] Do NOT touch `preview-smoke.yml` or `visual-diff.yml` — owned by `adopt-playwright-smoke` and `fix-vercel-deployment-protection-in-ci`. +- [ ] Do NOT add a `continue-on-error: true` to the new `forbidden-cors-headers` job — it is BLOCKING per Decision D5 (mirrors `forbidden-endpoints`). +- [ ] Do NOT broaden the grep in the new CI job to scan outside `pages/api/`. The convoy's scope is the API surface. If `lib/` or `components/` ever grows a CORS reference, that's a separate concern and a separate convoy. +- [ ] Do NOT run `npm audit fix` as part of this brief. The sweep does not change `package.json` or `package-lock.json`. + +## Rationale (≤3 sentences) + +The 24 wildcard CORS blocks across `pages/api/**` are scaffolding cruft from the original route templates; the same-origin Vercel deployment makes them serve no legitimate purpose, and the wildcard plus credential-stuffing rate-limit gap is the documented P0 #5 remainder from `fix-auth-bypass` Brief 4. A single mechanical sweep matches Brief 4's precedent shape exactly (same delete-the-3-setHeaders + delete-the-OPTIONS-if pattern, applied 24 times instead of 2) and is reviewable as one PR because every file's diff is structurally identical. Adding the `forbidden-cors-headers` CI job in the same PR locks the cleanup in — 24 files is enough surface that a future scaffold-style PR could easily re-introduce the pattern without the gate. diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index aaa1aa5..a3e3534 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -113,6 +113,35 @@ jobs: fi echo "OK: no forbidden dev endpoints under pages/api/." + forbidden-cors-headers: + name: No wildcard CORS in pages/api + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v4 + - name: Fail if any pages/api/ handler carries Access-Control-Allow-Origin + run: | + # The tcg-vault frontend and API are served from the same Vercel + # deployment (same origin), so CORS headers serve no purpose and + # are a documented attack surface (see .convoys/cors-tighten.md + # and AGENTS.md Gotcha #5).
