Published: 17 May 2022
Summary
CVE-2022-30964 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Multiselect Parameter. Its CVSS base score is 5.4 (Medium).
Operationally, ranked at the 44.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins Multiselect parameter Plugin 1.3 and earlier is affected by a stored cross-site scripting vulnerability (CWE-79). The plugin fails to escape the name and description fields of Multiselect parameters when those values are rendered on views that display build parameters, allowing malicious markup to be persisted and later executed in other users' browsers.
Attackers who possess Item/Configure permission on a Jenkins item can supply crafted parameter names or descriptions that are stored and subsequently served to any user who views the parameter configuration or build pages, resulting in execution of arbitrary script in the context of the Jenkins controller with a CVSS score of 5.4.
The Jenkins security advisory published on 2022-05-17 addresses the issue under SECURITY-2717 and provides the canonical reference for affected versions and remediation steps.
EPSS for the CVE rose from a low baseline to a peak of 0.2585 on 2025-12-11 before receding to the current value of 0.0022, indicating that exploitation interest increased well after initial disclosure.
