Joomla Extension - joomshaper.com - Missing CSRF Token Verification in Storefront Product Review Submission in Easy Store extension 1.0.0-3.0.0 - The product review submission endpoint (index.php?option=com_easystore&task=product.addReview) accepted submissions without verifying an anti-CSRF token (the check had been commented out in code).
