📝 Walkthrough

Walkthrough

The OIDC flow now evaluates consent through a dedicated endpoint. The frontend fetches and validates that result before auto-authorizing. Authorization request tickets are deleted before client lookup.

Changes

OIDC consent flow

Layer / File(s) Summary
Skip-consent endpoint and decision logic
internal/controller/controller.go, internal/controller/oidc_controller.go, internal/service/oidc_service.go, internal/controller/oidc_controller_test.go
The controller adds the skip-consent endpoint and response types. It returns whether the requested scopes are already granted. OIDC prompt values now provide string conversion. Tests cover endpoint responses and updated authorize behavior.
Frontend asynchronous authorization
frontend/src/pages/authorize-page.tsx, frontend/vite.config.ts
The authorization page fetches /api/oidc/skip-consent, validates its JSON response, and auto-authorizes when skipConsent is true. Loading and disabled states use the asynchronous flags.
Authorize-complete ticket invalidation
internal/controller/oidc_controller.go, internal/controller/oidc_controller_test.go
The flow deletes authorization request tickets immediately after retrieval. Tests cover successful exchange and unknown clients.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 6fe21

The change enables automatic OIDC authorization when prior consent exists, but the decision is made in a separate request from code issuance. If the signed-in account changes between those requests, authorization could proceed using the wrong account's consent; this bounded security risk should be fixed or explicitly accepted before merging.

104-141: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Gate automatic authorization and cancel the pending check.

While checkSkipConsent is pending, both buttons remain enabled. A manual authorizeMutate() call can therefore race with the callback's automatic call. The callback can also call authorizeMutate() after navigation unmounts the page because the fetch has no cleanup. Abort the fetch and guard the callback on cleanup. Track the checking state and disable authorization until the check completes. Cover both races with an integration test.

In `@frontend/src/pages/authorize-page.tsx` around lines 104 - 141, The
authorize-page flow around checkSkipConsent must prevent manual and automatic

cleanup, and guard the callback so it cannot call authorizeMutate after cleanup

- Around line 268-347: Refactor skipConsent so it retains only query binding,
authentication extraction, and JSON responses; move GetAuthorizeRequestByTicket,
GetOIDCConsent, prompt handling, and scopesGranted evaluation into a separate
controller method accepting context.Context, username, and OIDC ticket and
returning a typed consent-decision result. Have skipConsent invoke that method
and serialize its result, preserving all existing outcomes and error behavior
while removing decision logic’s dependency on gin.Context.
- Around line 268-274: Update OIDCController.skipConsent to set the response
header Cache-Control: no-store before every response path, including the
unconfigured and normal responses. Add a test that requests the same
authorization URL under two different identities and verifies the second request
receives a fresh consent decision rather than the first response.
