| Doc Text: |
A flaw was found in Jenkins. This vulnerability, identified as a stored cross-site scripting (XSS) issue, occurs because Jenkins does not properly escape the user-provided description for the "Mark temporarily offline" cause. An attacker with Agent/Configure or Agent/Disconnect permissions can exploit this to inject malicious scripts, leading to potential information disclosure or unauthorized actions within the user's browser.
