Summary

Upgrades the auth stack to clear every auth-related advisory and fixes the issues found while reviewing backend/src/auth.

Dependencies

• better-auth and @better-auth/passkey: 1.4.17 → 1.7.12 (backend + frontend)
• hono: 4.11.7 → 4.13.13
• Lockfile re-resolution also picks up patched kysely 0.29.7, @simplewebauthn/server 13.3.3 and defu 6.1.7
• pnpm audit --prod now reports no advisories for better-auth, @better-auth/*, hono, kysely, @simplewebauthn/server or defu

Before upgrading, the most relevant findings were account takeover via OAuth auto-link to an unverified email (CVE-2026-53516, exploitable only when admin credentials are not configured) and ReDoS in the Hono CORS middleware applied to every route (CVE-2026-69207).

No schema migration is needed: the hand-written tables in 001-base-schema.ts already match what 1.7.12 expects, including the passkey table. Better Auth 1.7 validates the schema at init, so a fresh database was verified to sign up and sign in, and a deliberately broken schema was confirmed to be rejected.

Fixes

• Stop logging the Set-Cookie header on sign-in and cookie names in the auth middleware, both of which leaked session tokens into debug logs
• Match ADMIN_EMAIL case-insensitively, since Better Auth stores lowercased emails
• Revoke the admin's sessions when ADMIN_PASSWORD_RESET rotates the password, atomically with the password write
• Remove the 5 minute session cookie cache. It served the signed cookie without reading the database, so a revoked session kept working until the cache expired: deleting every session row in a running container still returned 200 from /api/repos. Session state is now always authoritative, at the cost of one indexed SQLite read per authenticated request. A regression test fails if the cache returns
• Require userVerification for passkeys instead of preferring it

Upgrade fallout

• Hono 4.13 types c.req.param() as string | undefined; fixed in repo-git.ts and repo-terminal-socket.ts
• Five createAuth tests now use the real SQLite harness (createAuthDatabase) because Better Auth 1.7 needs a dialect it can detect

Validation

Clean Linux checkout, pnpm install --frozen-lockfile:

• pnpm typecheck: CLI, frontend and backend all pass
• pnpm lint: 0 errors (41 pre-existing warnings)
• Tests: CLI 503 pass, frontend 3264 pass, backend 3939 pass
  • 3 backend failures in session-sandbox ask for 8192 MiB on a host with 7.9 GiB; the service correctly rejects the request
• pnpm build: CLI, backend and frontend build

Container built from this branch and started in production mode:

• /api/health healthy with bundled OpenCode 2.0.15
• Registration disabled when admin is configured; /api/repos and /api/settings return 401 without a session; cross-site POST returns 403
• Mixed-case ADMIN_EMAIL signs in as admin@example.com with a single user row
• Passkey registration options report userVerification: "required"
• Static frontend and hashed assets serve correctly; no Set-Cookie appears in the logs
• ADMIN_PASSWORD_RESET leaves the old cookie unauthenticated and rejects the old password

Not included

Blocking sign-ups when ADMIN_EMAIL/ADMIN_PASSWORD are unset. Today registration is open and every account gets full access, which is what makes the OAuth auto-link advisory reachable; changing that alters who can create accounts, so it is left for a separate decision.

Better Auth also warns at startup that rate limiting cannot resolve a client IP behind the container proxy and falls back to one shared bucket per path. Fixing it needs advanced.ipAddress.ipAddressHeaders/trustedProxies configured to match the deployment, so it is left out of this change.

Summary by CodeRabbit

• Security

  • Passkey authentication now requires user verification.
  • Password resets immediately invalidate all active sessions, improving account security.
  • Administrative account matching now handles email addresses without regard to capitalization.
  • Authentication diagnostics no longer record cookie names, tokens, or response headers.

• Reliability

  • Improved handling for deleted sessions, repository identifiers, and terminal connections.
  • Added safeguards to preserve consistent session and authentication behavior during administrative updates.

📝 Walkthrough

Authentication behavior and dependencies changed, including passkey verification, authentication logging, and admin session handling. Repository ID parsing and missing terminal parameter handling also changed.

Changes: Authentication

Layer / File(s)	Summary
Authentication dependencies and passkey configuration backend/package.json, frontend/package.json, backend/src/auth/index.ts, backend/test/auth/index.test.ts	Authentication library versions were updated. Passkey user verification is now required. Authentication configuration tests use a local migrated in-memory database.
Authentication logging and admin synchronization backend/src/auth/middleware.ts, backend/src/routes/auth.ts, backend/test/auth/middleware-same-site.test.ts, backend/test/routes/auth.test.ts	Authentication logs no longer include cookie details or sign-in response headers. Admin lookup compares email addresses without case sensitivity. Password resets update credentials and delete the admin’s sessions in a transaction. Tests cover logging, session preservation, session revocation, and rollback.

Route Parameter Handling

Layer / File(s)	Summary
Repository and terminal route parameters backend/src/routes/repo-git.ts, backend/src/routes/repo-terminal-socket.ts	Repository ID parsing now uses Number.parseInt with radix 10. A missing terminal ptyID is converted to an empty string.
