Medium (5.4). EPSS 1.3% chance of exploitation in the next 30 days. Fixed in org.jenkins-ci.main:jenkins-core 2.164.2, 2.172.
The f:validateButton form control for the Jenkins UI did not properly escape job URLs in Jenkins 2.171 and earlier and Jenkins LTS 2.164.1 and earlier, resulting in a cross-site scripting (XSS) vulnerability exploitable by users with the ability to control job names.
