## Technical details

This vulnerability is a Cross-Site Request Forgery (CSRF) issue in YOOtheme Zoo versions before 4.1.66, where front-end state-changing operations lack proper CSRF token validation. An attacker can craft a malicious webpage or email that, when visited by an authenticated Zoo user, silently executes state-changing actions without the user's explicit consent. The attack vector is network-based and requires no special privileges, though it does require the user to be authenticated and visit an attacker-controlled page while logged in. Affected versions prior to 4.1.66 are vulnerable; users should upgrade to 4.1.66 or later to remediate.
