Published: 23 June 2022
Summary
CVE-2022-34187 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Filesystem List Parameter. Its CVSS base score is 5.4 (Medium).
Operationally, ranked in the top 11.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins Filesystem List Parameter Plugin 0.0.7 and earlier is affected by a stored cross-site scripting vulnerability. The plugin fails to escape the name and description fields of File system objects list parameters when rendering parameter views, allowing malicious markup to persist in the Jenkins UI. The issue is tracked as CWE-79 with a CVSS 3.1 score of 5.4.
Attackers holding Item/Configure permission can supply crafted parameter names or descriptions that execute scripts in the browsers of other users who later view the affected job configuration or build parameters. Because the payload is stored, the attacker does not need to interact directly with each victim.
The Jenkins security advisory published on 2022-06-22 at https://www.jenkins.io/security/advisory/2022-06-22/#SECURITY-2784 addresses the issue.
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 0.0425, indicating a period of increased exploitation interest after disclosure.
