Keeps provider details consistent across settings read, write, and log paths.\n\nRelated to OS-981.\nDepends on #2098 for shared dependency resolutions.\nVerification: lint, type-check, build.

Summary by CodeRabbit

  • Security
    • OIDC client secrets are excluded from settings and provider query responses, including settings update results.
  • Bug Fixes
    • Updating an OIDC provider without a client secret preserves the existing secret when the provider is matched by its ID or connection details. Other provider settings remain available.

Walkthrough

Settings and OIDC provider query responses redact client secrets. OIDC configuration updates match existing providers by ID or client ID and endpoint values, then retain the existing secret when the submitted value is omitted.

Changes

OIDC client secret handling

Layer / File(s) Summary
Redact secrets in responses
api/src/unraid-api/graph/resolvers/sso/models/oidc-provider.model.ts, api/src/unraid-api/graph/resolvers/settings/settings.resolver.ts, api/src/unraid-api/graph/resolvers/sso/sso.resolver.ts
The shared helper removes clientSecret from provider objects. Settings values, update logs and results, and OIDC provider queries apply redaction.
Preserve omitted provider secrets
api/src/unraid-api/graph/resolvers/sso/core/oidc-config.service.ts
Provider updates match an existing provider by ID or by client ID and issuer, authorization endpoint, and token endpoint. When the incoming secret is omitted, the update retains the matched provider’s secret.

Priority: ➖ Normal

Change: Bug fix

Merge Risk: ⚪ Minimal · up to acf61

Provider responses omit secrets, while updates retain existing secrets when omitted. No actionable merge-blocking issue was established; mergeable subject to normal checks.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to a0447

Secret redaction improves credential protection, and existing configuration permissions remain in place. However, provider matching can confuse credential ownership when multiple records share client details, potentially disrupting sign-in configuration.

Retained concerns

  • Medium · security · inferred: Provider reconciliation does not prioritize an exact unique-ID match over a composite client-and-endpoint match. If an earlier provider shares the submitted client details, settings updates can restore that earlier record's secret instead of the exact-ID owner's secret. The upsert path can also replace the earlier record, potentially creating duplicate IDs and disturbing credential or authorization-policy associations. This newly introduced ambiguity threatens credential ownership and login continuity; configuration-write permission is still required.
Security review details

Security Blast Radius

  • inferred — The demonstrated affected scope is the server's persisted OIDC provider credentials and login configuration. The externally traced update path requires CONFIG UPDATE_ANY permission; unauthenticated callers are not shown gaining provider-write authority through this change.

Security Findings and Attack Paths

  • inferred — The retained concern is a conditional state-ownership failure: with two existing records sharing client ID and endpoint values, a privileged save omitting the secret can select the earlier record rather than the exact-ID owner. The newly restored credential then enters persisted configuration and downstream OIDC client authentication. This does not establish an unauthenticated exploit or an additional privilege gain.

Trust Boundaries and Controls

  • observed — Checked configuration queries and settings writes retain existing permission checks, while public login-button data uses a display-only allowlist. Settings input logs, updated-value logs, and checked configuration responses now exclude OIDC clientSecret.
  • inferred — Same-ID updates can preserve a secret while changing endpoints. This alone does not establish a new credential-exfiltration capability for configuration administrators: the base already allowed those callers to read stored secrets and modify configuration.

Resilience and Maintainability Implications

  • observed — The pre-existing persistence flow updates in-memory configuration before awaiting persistence and does not inspect the returned boolean. The shared writer returns false on validation or write failure, and startup reloads disk state with migration/default fallbacks. These existing behaviors limit failure and recovery guarantees, but the inspected base/head comparison does not establish that this PR introduced them.

Hardening Proposals

  • proposed — Resolve exact provider IDs before any composite fallback, reject ambiguous fallback matches, and define whether endpoint or ID changes preserve credential ownership. When reconciliation changes an ID, invalidate both old and new cache identities.

A rabbit guards the secret key,
And keeps it from each query’s view.
If updates leave the secret blank,
The matched provider keeps its rank.
Safe settings hop along the way,
While carrot crumbs mark secret’s stay.

P1 Badge Keep protected GraphQL operations schema-valid

Removing this field makes the existing clientSecret selections in authorization.guard.graphql.spec.ts invalid during GraphQL validation. The four affected protected-operation cases will now return validation errors before the authorization guard runs, so both their expected FORBIDDEN assertions and their ADMIN success assertions fail. Update those queries to select a valid field while retaining the authorization-boundary coverage.

P1 Badge Preserve secrets when provider IDs change

When an administrator edits an existing custom provider's ID in the settings form, values() has already omitted its secret and this lookup uses the new ID, so it cannot find the old provider to restore that secret. The subsequently persisted provider has no clientSecret, which breaks client-secret OIDC providers on their next authentication attempt. Match against the provider's prior identity or disallow ID changes once a provider is configured.

Checked against the current branch: the update path now matches by existing provider ID or the stable OIDC identity (client ID, issuer, authorization endpoint, and token endpoint) before restoring an omitted client secret. The provider-save path applies the same matching, so changing an ID does not drop the stored secret. No further source change is needed for this comment.

- Line 287: At oidc-config.service.ts lines 287-287, update the provider
selection to search for an exact ID match first, using the client-and-endpoint
fallback only when no ID match exists, then derive the replacement index from
that result. Apply the same ID-first selection at lines 437-437 before retaining
an existing secret.
