Deeper analysis
The Jenkins List Git Branches Parameter Plugin 0.0.9 and earlier contains a stored cross-site scripting vulnerability because the plugin fails to escape the name of the "List Git branches (and more)" parameter. The issue is tracked as CVE-2022-27212 with a CVSS 3.1 score of 5.4 and is classified under CWE-79.
Attackers who possess Item/Configure permission on a Jenkins instance can supply a malicious parameter name that is stored and later rendered for other users, resulting in script execution with limited impact on confidentiality and integrity in a changed scope.
The Jenkins security advisory for SECURITY-2167, referenced in oss-security mailing list postings from March 2022, documents the flaw and corresponding updates. The associated EPSS score rose sharply from a low baseline to a peak of 0.3160 on 2025-12-11 before receding to the current value of 0.0021, indicating that exploitation interest developed well after initial disclosure.
