fix(auth): require explicit GraphQL authorization - #2074
Conversation
WalkthroughThe PR adds a GraphQL-specific authorization guard, requires explicit metadata on resolver handlers, protects previously unguarded resolvers, adds lint enforcement, and expands tests for permissions, authentication, public access, nested fields, REST behavior, and secret-bearing responses. ChangesGraphQL authorization enforcement
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to GraphQL permission metadata with empty values can pass the new lint enforcement, allowing future handlers to appear protected without a usable permission definition. Tightening validation before merge keeps the authorization coverage guarantee reliable. Sequence Diagram(s)sequenceDiagram

Reject explicit empty permission values.
Line 45 accepts @UsePermissions({ action: undefined, resource: undefined }) because both keys exist. The rule then reports no error for unusable permission metadata. Require non-empty values for both properties, while still allowing enum expressions. Add invalid fixtures for undefined, null, and empty-string values.

Summary
Enforce explicit authorization on GraphQL handlers so an authenticated read-only key cannot perform notification writes, change UPS shutdown configuration, or retrieve persisted OIDC client secrets.
Work intent: address the reported GraphQL authorization gaps and prevent missing permission decorators from reopening them. Related notification report: #2065.
Resolution
Extend the existing
nest-authzguard to deny GraphQL handlers with missing or empty permission metadata. Keep Casbin as the permission authority and preserve existing REST behavior. Public login queries retain explicit public access; empty mutation namespaces require authentication and leave operation permissions to their child handlers.Add permissions to notification operations, UPS queries/subscriptions/configuration, settings fields, and flash-backup initiation. Complete the corresponding nested-field permissions in the API and bundled Connect plugin so default-deny preserves supported reads.
Add
unraid-auth/require-graphql-authorizationto ESLint and run its focused audit over API and bundled-plugin source from bothlintandlint:fix. It follows decorator imports, including aliases and namespaces, requires method-level access metadata, and rejects empty permission declarations. Test fixtures and generator templates are excluded. The rule has no automatic permission fix.Reviewer considerations
CONFIG / READ_ANY. Secret-bearing settings values and OIDC provider/configuration queries therefore requireCONFIG / UPDATE_ANY, including existing root OIDC queries. Ordinary configuration reads retain read permission.Verification
pnpm --filter ./api coverage— full API run passed: 2,159 tests across 186 passing suites. The lint configuration integration tests allow 30 seconds for cold ESLint startup under concurrent CI coverage load; unit-test timeouts remain unchanged.pnpm --filter ./api test eslint/require-graphql-authorization.spec.ts src/unraid-api/auth/resolver-authorization.spec.ts src/unraid-api/auth/authorization.guard.graphql.spec.ts— 69 tests passed, including 34 lint-rule/config tests.pnpm --filter ./api lint— passed with the new API/plugin authorization pass. A CLI negative check with temporary unguarded API and plugin endpoints failed with both expected lint errors; fixtures were removed.pnpm --filter ./api test src/unraid-api/auth src/unraid-api/graph/resolvers/notifications src/unraid-api/graph/resolvers/ups src/unraid-api/graph/resolvers/settings src/unraid-api/graph/resolvers/sso src/unraid-api/app/__test__/app.module.integration.spec.ts— 610 tests passed across 31 suites.Final resolver metadata audit rerun after expanding module-provider discovery — passed.
pnpm --filter ./api lintandpnpm --filter ./api type-check— passed; the final audit file also passed targeted lint.pnpm --filter ./api buildandpnpm --filter unraid-api-plugin-connect build— passed.Coverage includes real HTTP GraphQL requests with aliases and fragments, denial before service invocation, ADMIN and scoped-key access, public login, read-only monitoring, missing/empty metadata, and nested mutation authorization. Device services use test doubles; no live UPS configuration was changed.
QA VM verification (2026-09-05)
Tested the pinned CI plugin on DGTest01 running Unraid 7.3.2; live API reported
4.37.3+0b90b741(merge build containingb2976cefe). All 38 GUEST/VIEWER denial checks passed, covering all notification mutations, UPS writes, flash backup, sensitive settings/OIDC queries, API keys, and nested parity operations. ADMIN and notification-scoped keys completed notification writes; VIEWER monitoring/configuration reads remained accessible. A persisted synthetic OIDC secret was readable by ADMIN and blocked from VIEWER, including aliases/fragments; public login queries remained accessible without exposing the secret.The VM has no physical UPS or configured UPS service: denied writes left configuration unchanged, but successful ADMIN UPS writes and shutdown behavior were not tested. An existing notification ID mismatch required using the persisted ID from the notification list for archive/unread/delete; the service code producing that mismatch is unchanged by this PR.
Temporary keys and notifications were removed, SSO settings restored, and the provider restored and released the VM. Final status: available, powered off, drive-free.
Release note
Fix GraphQL authorization gaps affecting notifications, UPS configuration, and OIDC settings. Require explicit authorization metadata on GraphQL plugin handlers.
