What is CVE-2021-21668?

The Jenkins Scriptler Plugin, specifically versions 3.1 and earlier, is susceptible to a stored cross-site scripting (XSS) vulnerability. This issue arises because the plugin fails to appropriately escape script content, allowing attackers who have Scriptler/Configure permissions to inject malicious scripts. Such vulnerabilities can potentially lead to unauthorized actions executed within users' sessions, making it crucial for organizations to review their installations and implement the necessary updates to mitigate the risk.
