Deeper analysis
The vulnerability is a stored cross-site scripting flaw, tracked as CVE-2022-34790 and CWE-79, that affects the Jenkins eXtreme Feedback Panel Plugin in versions 2.0.1 and earlier. It arises because the plugin fails to escape job names rendered inside tooltips, allowing untrusted content to be stored and later displayed to users.
Attackers who hold Item/Configure permission can exploit the issue by setting job names that contain malicious scripts. Successful exploitation results in script execution within the browser of other users who view the affected panel, producing a CVSS 5.4 impact that affects confidentiality and integrity in a limited, cross-origin scope while leaving availability untouched.
The issue is documented in the Jenkins security advisory published on 2022-06-30 under identifier SECURITY-1939. The EPSS probability rose from a low baseline to a recorded peak of 0.1267 on 2025-12-11 before receding to its current value of 0.0801.
