Name of the Vulnerable Software and Affected Versions Jenkins SSH Agent Plugin versions 1.23 and earlier Jenkins SSH Agent Plugin versions prior to 1.23.2 and 1.22.1

Description The issue is related to missing permission checks in the Jenkins SSH Agent Plugin, which allows attackers with Overall/Read access to enumerate credentials IDs of credentials stored in Jenkins. These credentials IDs can be used as part of an attack to capture the credentials using another vulnerability.

Recommendations For Jenkins SSH Agent Plugin versions 1.23 and earlier, update to version 1.23.2 or later. For Jenkins SSH Agent Plugin versions prior to 1.22.1, update to version 1.22.1 or later. As a temporary workaround, consider restricting access to the plugin's HTTP endpoints to minimize the risk of exploitation.
