Deeper analysis
Jenkins JDK Parameter Plugin 1.0 and earlier is affected by a stored cross-site scripting vulnerability. The plugin fails to escape the name and description fields of JDK parameters when rendering parameter views, allowing malicious script content to be persisted and later executed in users' browsers. The issue is tracked as CWE-79 with a CVSS 3.1 score of 5.4.
Attackers who possess Item/Configure permission on a Jenkins job can supply crafted parameter names or descriptions that are stored and served to other users viewing the job configuration or build pages, resulting in script execution in the context of those users' sessions.
The Jenkins security advisory published on 2022-05-17 details the flaw under SECURITY-2717 and directs administrators to update the JDK Parameter Plugin to a version that properly escapes parameter metadata.
EPSS for this CVE rose from a low baseline after disclosure to a peak of 0.3160 on 2025-12-11 before receding to the current value of 0.0022, indicating a period of increased exploitation interest that warrants renewed attention.
