Until an official fix is available, restrict access and control over Jenkins agent processes to trusted users only to reduce the risk of exploitation.
Description
A cross-site scripting (XSS) vulnerability exists in Jenkins versions 2.587 and earlier, including LTS 2.580.1 and earlier. The vulnerability arises because the URL of the link shown in the workspace browser for each file and directory is computed on the agent side, which can be exploited by attackers who control agent processes.
