Technical details
The product review submission endpoint (index.php?option=com_easystore&task=product.addReview) accepted submissions without verifying CSRF tokens because the token check was commented out in the ProductController. An attacker could craft a malicious page to submit reviews on behalf of authenticated users. The fix enforces Session::checkToken() validation in the controller and injects token fields into the review form template.
