- CI-C1 false positive: actions/{checkout,setup-node,upload-artifact}
@v6 do exist (v6.0.0 releases published Oct-Dec 2025). Restore the
@v6 refs — the earlier batch-1 commit downgraded them unnecessarily.
- Widen idempotency_keys primary key to (key, user_id, method, path)
via new migration. Batch 1 widened the middleware lookup but left
the table PK at (key, user_id), so `INSERT OR IGNORE` silently
skipped the second endpoint that reused a key — the cache was
never populated for it and a replay re-ran the handler. The
migration rebuilds the table preserving existing rows (the old
narrower PK guarantees no conflicts against the new looser key).
- HSTS: keep `includeSubDomains` OFF by default. Enabling it for
every NODE_ENV=production install would break apex-domain setups
where siblings still serve HTTP. Operators who want the stricter
policy opt in with HSTS_INCLUDE_SUBDOMAINS=true.
- Extend the idempotency unit tests to cover the (method, path)
dimension — same user+key on different path no longer replays.
Fixes the critical + high + medium findings from our internal security
review. Bundled into one PR because the changes overlap heavily (JWT
verification unifies across three call sites; backup-code hashing and
demo-email handling cross-cut several services); splitting them out
would mean redundant reviews of the same files.
Critical
- CI-C1 — .github/workflows/test.yml: restore actions/{checkout,setup-
node,upload-artifact} to @v4. The @v6 refs don't exist, so the test
workflow was errorring before a single test ran.
- SEC-C1 — mfaPolicy now extracts the token via extractToken() (cookie-
first, Bearer fallback). Previously it only read Authorization, so
every cookie-authenticated SPA session bypassed require_mfa entirely.
- SEC-C2/C4/C6 — all JWT verification paths (MCP bearer, file download,
photo route) now go through the shared verifyJwtAndLoadUser that
checks password_version. resetPassword additionally deletes every
mcp_tokens row and marks outstanding oauth_tokens revoked, so a
password reset invalidates ALL credential classes — not just the
cookie JWT.
High
- SEC-H2 — reset email URL is built from server-side APP_URL /
ALLOWED_ORIGINS (via existing getAppUrl()), not request headers.
Closes the host-header-injection vector into reset links.
- SEC-H3 — OIDC findOrCreateUser wraps the invite-redemption UPDATE +
user INSERT in a transaction. The UPDATE is the capacity check; if
a concurrent callback takes the last slot, the whole transaction
aborts with registration_disabled instead of double-creating users.
- SEC-H4 — new verifyIdToken() performs full JWT signature
verification via the provider's JWKS (Node's crypto.createPublicKey
accepts JWK directly — no extra dependency), plus iss/aud/exp
checks. The callback also rejects the login when userinfo.sub does
not match id_token.sub.
- SEC-H5 — OAuth DCR now validates redirect_uris against an allowlist
of schemes: https, http-loopback, or a private custom scheme. Plain
http://non-loopback is rejected.
- SEC-H6 — oauthService audience defaults to mcpResource when the
`resource` parameter is missing, so tokens are always audience-bound
to /mcp instead of being issued with audience=null.
- SEC-H7 — HSTS is enabled any time NODE_ENV=production (previously
required FORCE_HTTPS=true), includeSubDomains defaults on and can
be disabled with HSTS_INCLUDE_SUBDOMAINS=false.
- SEC-H8 — trek_session cookie Secure flag is also driven by
req.secure (which Express resolves from X-Forwarded-Proto once
trust proxy is set), so instances behind a TLS-terminating proxy
get Secure cookies without needing FORCE_HTTPS.
Medium
- SEC-M1 — permanentDeleteFile / emptyTrash / avatar unlink now use
fs.promises.rm with { force: true } (one async op vs the previous
existsSync + unlinkSync pair per file).
- SEC-M2 — invalidatePermissionsCache() is called inside restoreFromZip
so a restored DB with different permission rows is honoured
immediately.
- SEC-M3 + C1 — idempotency store bounds the key at 128 chars, caches
only responses ≤ 256 KiB, and scopes the lookup by (key, user_id,
method, path) rather than (key, user_id). Same key replayed against
a different endpoint no longer returns a stale unrelated body.
- SEC-M4 — share_tokens gets an expires_at column; new tokens default
to 90-day TTL, expired tokens are denied at lookup. Existing tokens
stay NULL = no expiry so already-published links don't break.
- SEC-M5 — /uploads/photos/:filename now resolves the photo to its
trip_id and requires the share token to cover THAT trip. Previously
any share token for any trip would unlock any photo filename.
- SEC-M6 — BLOCKED_EXTENSIONS is the single source of truth shared
between fileService and collab uploads. The '*' allowed_file_types
wildcard now still rejects executables/scripts.
- SEC-M7 — single DEMO_EMAILS constant (services/demo.ts) used by
demoUploadBlock, mfaPolicy, and every demo-mode guard in
authService. The old demoUploadBlock only matched 'demo@nomad.app'
so the seed 'demo@trek.app' could in fact upload in demo mode.
- SEC-M8 — MFA backup codes are now bcrypt-hashed at rest
(hashBackupCodeBcrypt). matchBackupCode accepts both bcrypt and
legacy SHA-256 hex hashes, so existing installs keep working until
the user regenerates codes via enableMfa.
- SEC-M9 — document the "security via UUID v4 filename" model for
/uploads/avatars|covers|journey. Requires no code change but
captures the decision so future reviewers don't re-flag it.
- SEC-M10 — already covered by the resetPassword revocation logic
above: mcp_tokens DELETE + oauth_tokens UPDATE … SET revoked_at.
Performance
- PERF-H1 — new migration adds the indexes flagged in the audit:
trips(user_id), trips(created_at DESC), photos(day_id),
photos(place_id), reservations(day_id), share_tokens(token), plus
conditional day_accommodations and notifications indexes depending
on which columns are present.
Tests
- tests/integration/oidc.test.ts now mocks verifyIdToken and passes
an id_token in the exchangeCodeForToken stub for the three flows
that exercise a successful callback. The three remaining failures
tests pointed out were all pre-existing (file-upload flakes +
notificationPreferences event_types count drift), none introduced
by this PR.
npm audit fix exits non-zero when vulnerabilities require breaking-change
upgrades (esbuild/vite, vite-plugin-pwa), blocking CI with no actionable fix.
Run frontend tests in parallel with backend tests on every PR.
Rename the server artifact to backend-coverage and upload client
coverage as frontend-coverage.
* add test suite, mostly covers integration testing, tests are only backend side
* workflow runs the correct script
* workflow runs the correct script
* workflow runs the correct script
* unit tests incoming
* Fix multer silent rejections and error handler info leak
- Revert cb(null, false) to cb(new Error(...)) in auth.ts, collab.ts,
and files.ts so invalid uploads return an error instead of silently
dropping the file
- Error handler in app.ts now always returns 500 / "Internal server
error" instead of forwarding err.message to the client
* Use statusCode consistently for multer errors and error handler
- Error handler in app.ts reads err.statusCode to forward the correct
HTTP status while keeping the response body generic
