Medium (5.4) in jenkins custom build properties. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in io.jenkins.plugins:custom-build-properties 2.82.v16d5b.
Jenkins Custom Build Properties Plugin 2.79.vc095ccc85094 and earlier does not escape property values and build display names on the Custom Build Properties and Build Summary pages, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to set or change these values.
