CVE-2025-66109Network attack vector

Unauthorized tracker action via missing nonce

Published Nov 21, 2025 · Updated Nov 21, 2025

Missing authorization in Octolize Cart Weight for WooCommerce 1.9.11 and earlier allows remote attackers to invoke the tracker agree action. The action accepted requests without verifying a WordPress nonce, so it did not validate that the request originated from an authorized administrative workflow. The public record does not disclose the tracker data exposed or the exact state change performed, limiting the established consequence to unauthorized access to that action.
