Description

Jenkins OpenId Connect Authentication Plugin 4.354.v321ce67a_1de8 and earlier does not check the iss (Issuer) claim of an ID Token during its authentication flow, a value that identifies the Originating Party (IdP).

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 iss (Issuer) claim of an ID Token during its authentication flow when the Issuer is known.

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 CVE-2024-47807 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.
