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). An attacker could trick a logged-in user into posting unauthorized reviews or submitting review spam via cross-site requests. Resolved by enforcing Session::checkToken('request') / Session::checkToken('post') in ProductController, injecting HTMLHelper::_('form.token') into the review form template, and appending the session token to the submission payload in review-form.js.
