Addresses CWE-598: long-lived JWTs were exposed in WebSocket URLs, file
download links, and Immich asset proxy URLs, leaking into server logs,
browser history, and Referer headers.
- Add ephemeralTokens service: in-memory single-use tokens with per-purpose
TTLs (ws=30s, download/immich=60s), max 10k entries, periodic cleanup
- Add POST /api/auth/ws-token and POST /api/auth/resource-token endpoints
- WebSocket auth now consumes an ephemeral token instead of verifying the JWT
directly from the URL; client fetches a fresh token before each connect
- File download ?token= query param now accepts ephemeral tokens; Bearer
header path continues to accept JWTs for programmatic access
- Immich asset proxy replaces authFromQuery JWT injection with ephemeral token
consumption
- Client: new getAuthUrl() utility, AuthedImg/ImmichImg components, and async
onClick handlers replace the synchronous authUrl() pattern throughout
FileManager, PlaceInspector, and MemoriesPanel
- Add OIDC_DISCOVERY_URL env var and oidc_discovery_url DB setting to allow
overriding the auto-constructed discovery endpoint (required for Authentik
and similar providers); exposed in the admin UI and .env.example
- Add { algorithms: ['HS256'] } to all jwt.verify() calls to prevent
algorithm confusion attacks (including the 'none' algorithm)
- Add { algorithm: 'HS256' } to all jwt.sign() calls for consistency
- Reduce OIDC token payload to only { id } (was leaking username, email, role)
- Validate OIDC redirect URI against APP_URL env var when configured
- Add startup warning when JWT_SECRET is auto-generated

Add an admin-controlled `require_mfa` policy in App Settings and expose it via `/auth/app-config` so the client can enforce it globally. Users without MFA are redirected to Settings after login and blocked from protected API/WebSocket access until setup is completed, while preserving MFA setup endpoints and admin recovery paths. Also prevent enabling the policy unless the acting admin already has MFA enabled, and block MFA disable while the policy is active. Includes UI toggle in Admin > Settings, required-policy notice in Settings, client-side 403 `MFA_REQUIRED` handling, and i18n updates for all supported locales.
