CVE-2022-46686 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Custom Build Properties. Its CVSS base score is 5.4 (Medium).
Operationally, ranked in the top 7.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins Custom Build Properties Plugin 2.79.vc095ccc85094 and earlier contains a stored cross-site scripting vulnerability because the plugin does not escape property values and build display names when rendering the Custom Build Properties and Build Summary pages. The affected component is the Jenkins plugin that allows users to attach custom metadata to builds.
Attackers with permission to set or modify these property values or display names can inject malicious scripts that execute in the browsers of other users who view the affected pages. Successful exploitation yields limited impact on confidentiality and integrity with no availability effect, consistent with the reported CVSS 5.4 score.
The Jenkins security advisory published on 2022-12-07 under identifier SECURITY-2810 describes the issue and is available at the referenced URL.
EPSS scores have remained low, with a current value of 0.0898 and a modest peak of 0.1037.
