CVE-2025-64136: Jenkins Themis Plugin vulnerable to cross-site request forgery

October 29, 2025 (updated November 5, 2025)

Jenkins Themis Plugin 1.4.1 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to connect to an attacker-specified URL.

Additionally, this endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

As of publication of this advisory, there is no fix.
