What is CVE-2020-2290?

The Jenkins Active Choices Plugin, specifically versions 2.4 and earlier, contains a vulnerability that allows attackers to exploit stored cross-site scripting (XSS). This occurs due to the failure to properly escape certain return values from sandboxed scripts in Reactive Reference Parameters, enabling attackers with Job/Configure permission to execute malicious scripts. These actions can compromise user sessions and potentially lead to further exploitation within the Jenkins environment.

Affected Version(s)
