Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-79.

Summary

Jenkins 2.587 and earlier, and LTS 2.580.1 and earlier, allow agents to send exceptions that implement the Stapler HttpResponse interface to the controller. This causes cross-site scripting (CWE-79). An attacker who controls agent processes can exploit it, and a user must interact with a page for the attack to succeed.
