Description

Jenkins OpenId Connect Authentication Plugin 4.354.v321ce67a_1de8 and earlier does not check the aud (Audience) claim of an ID Token during its authentication flow, a value to verify the token is issued for the correct client.

This vulnerability may allow attackers to subvert the authentication flow, potentially gaining administrator access to Jenkins.

OpenId Connect Authentication Plugin 4.355.v3a_fb_fca_b_96d4 checks the aud (Audience) claim of an ID Token during its authentication flow.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:oic-auth, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:oic-auth to 4.355.v3a or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-49hx-9mm2-7675 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
