Vulnerability in org.jenkins-ci.tools:git-parameter (CVE-2026-57286)

Summary

Vulnerability in org.jenkins-ci.tools:git-parameter (CVE-2026-57286). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 462.463 or later.

Original description

The description as published by the source.

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.
