CVE-2025-64136Network attack vector

Attacker-controlled connections via GET-capable HTTP endpoint

Published Oct 29, 2025 · Updated Oct 29, 2025

Cross-site request forgery in Jenkins Themis Plugin 1.4.1 and earlier allows remote attackers to make Jenkins connect to chosen servers. The connection-test HTTP endpoint accepts state-changing requests without requiring POST, so a crafted page can make a victim's browser submit an attacker-chosen URL. Exploitation requires user interaction and a victim session with Overall/Read permission; the bounded impact is an outbound server connection.
