CVE-2021-21700

Name of the Vulnerable Software and Affected Versions Jenkins Scriptler Plugin versions 3.3 and earlier

Description The issue is related to a stored cross-site scripting (XSS) vulnerability. It occurs because the Jenkins Scriptler Plugin does not escape the name of scripts on the UI when asking to confirm their deletion. This makes it exploitable by attackers who are able to create Scriptler scripts.

Recommendations For Jenkins Scriptler Plugin versions 3.3 and earlier, update to version 3.4 or later, which escapes the name of scripts on the UI when asking to confirm their deletion.
