Description

Jenkins Git Parameter Plugin 462.vdcf3df2ed2ca_ and earlier does not perform a permission check in an HTTP endpoint that populates the list of values for Git parameters by querying the SCM configured on a job, using the SCM credentials configured in Jenkins.

This allows attackers with Item/Read permission to obtain information about the SCM repository used by a job they would otherwise be unable to access, such as branch names, tag names, and revision metadata.

Git Parameter Plugin 462.463.v496a_59f698e5 requires Item/Build permission to populate the list of values for Git parameters.

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.tools:git-parameter, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.tools:git-parameter to 462.463 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hwvp-7xqv-8jx3 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.
