Technical details
A Cross-Site Request Forgery (CSRF) vulnerability exists in the backend cleanup actions of Event Gallery versions before 6.5.0. The vulnerability allows an unauthenticated attacker to craft a malicious request that, when visited by an authenticated administrator, triggers cleanup operations (deletion of orphaned files and shopping carts older than 30 days) without proper CSRF token validation. This requires the administrator to be logged into the Joomla backend and visit the attacker-controlled page.
