Summary

CVE-2022-34190 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Maven Metadata. Its CVSS base score is 5.4 (Medium).

Operationally, ranked in the top 3.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

The vulnerability is a stored cross-site scripting flaw (CWE-79) in the Jenkins Maven Metadata Plugin for Jenkins CI server, versions 2.1 and earlier. The plugin does not escape the name and description fields of List maven artifact versions parameters when rendering them on views that display parameters, producing a medium-severity issue with CVSS 5.4.

Attackers who hold Item/Configure permission can supply crafted parameter values that are stored and later executed in the browsers of other users who view the affected pages, resulting in limited impacts to confidentiality and integrity within the Jenkins instance.

The Jenkins project published a security advisory on 2022-06-22 that addresses the issue under SECURITY-2784 and is available at the referenced URL. The EPSS score has remained flat at its peak value of 0.2958 with no material increase after disclosure.
