Name of the Vulnerable Software and Affected Versions Jenkins Custom Checkbox Parameter Plugin versions 1.4 and earlier

Description The issue results in a stored cross-site scripting (XSS) vulnerability, which can be exploited by attackers with Item/Configure permission. This occurs because the plugin does not escape the name and description of Custom Checkbox Parameter parameters on views displaying parameters. Exploitation requires that parameters are listed on another page and that those pages are not hardened to prevent exploitation. It is noted that Jenkins (core) has prevented exploitation of vulnerabilities of this kind on certain pages since version 2.44 and LTS 2.32.2.

Recommendations For Jenkins Custom Checkbox Parameter Plugin versions 1.4 and earlier, update to a version later than 1.4 to resolve the issue. As a temporary workaround, consider restricting access to the Build With Parameters and Parameters pages provided by Jenkins (core) until a patch is available. Additionally, ensure that any pages listing parameters are hardened to prevent exploitation.
