Technical details
The vulnerability is a CSRF flaw in multiple cart action handlers within the Event Gallery extension prior to version 6.5.0. The affected cart operations lack proper CSRF token validation, allowing an attacker to submit forged requests on behalf of an authenticated user. No authentication bypass is required beyond social engineering a user to visit a malicious site while logged into the Joomla site.
