Status: published. Published: 2026-10-28. Updated: 2026-11-05.

Jenkins 2.587 and earlier, LTS 2.580.1 and earlier allows agents to send exceptions implementing the Stapler HttpResponse interface to the controller, resulting in a cross-site scripting (XSS) vulnerability exploitable by attackers in control of agent processes.

## Remediation
