CVE-2025-31721

Description

Jenkins 2.503 and earlier, LTS 2.492.2 and earlier does not perform a permission check in an HTTP endpoint. This allows attackers with Computer/Create permission but without Computer/Configure permission to copy an agent, gaining access to encrypted secrets in its configuration. This is due to an incomplete fix of [SECURITY-3495](https://www.jenkins.io/security/advisory/2025-03-05/#SECURITY-3495)/CVE-2025-27622. Jenkins 2.504, LTS 2.492.3 requires Computer/Configure permission to copy an agent containing secrets.
