📝 WalkthroughWalkthroughDenied consent verification now returns the decoded flow. The OAuth2 handler uses it to mark the related device-code session as rejected and logs lookup or update failures. ChangesDevice consent rejection
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to Denied device consent now causes device-code polling to return access_denied instead of waiting for expiration. No actionable merge-blocking risk remains; adding an end-to-end regression test is a non-blocking follow-up. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Add an end-to-end device-flow denial regression test.
The device-flow tests cover successful polling but not consent denial. Deny consent, poll the token endpoint, and assert access_denied instead of authorization_pending.

Summary
Fixes #4110 — when a user denies the consent prompt during the OAuth 2.0 Device Authorization Grant (RFC 8628) flow, the device-code token poll keeps returning
authorization_pendinguntil thedevice_codeexpires. The expectedaccess_deniedis never returned, so the polling client (e.g. a CLI) appears to hang for the fulldevice_codelifetime instead of failing fast.Root Cause
fosite/handler/rfc8628/token_handler.goalready handles theUserCodeRejectedstate and returnsaccess_denied:However, nothing in Hydra ever transitions a device session into
UserCodeRejected. The only writer of the state is the accept path inoauth2/handler.go(performOAuth2DeviceVerificationFlow):On the deny path,
consent/strategy_default.go::verifyConsentdetects the denied consent, returns the RFC error, and the flow is discarded — the device session is left atUserCodeUnused, so the token poll keeps returningauthorization_pending.Changes
1.
consent/strategy_default.go—verifyConsentWhen
f.ConsentError.IsError()(the consent was denied), return the flow alongside the error so that callers can identify the device code session and propagate the rejection. The auth-code caller (HandleOAuth2AuthorizationRequest) discards the flow on error, so this is safe.2.
oauth2/handler.go—performOAuth2DeviceVerificationFlowOn the error path, check if the flow is a device authorization flow (
f.DeviceCodeRequestID.Valid). If so, transition the device code session toUserCodeRejected— mirroring the existingUserCodeAcceptedtransition on the accept path.This ensures that the polling token client receives
access_denied(RFC 8628 §3.5) on its next poll instead of hanging until the device code expires.Testing
