Description

The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 5.127.0 via the 'search' parameter of the cr_show_more_all_reviews and cr_show_more_reviews AJAX actions. This is due to the handlers being hooked on wp_ajax_nopriv_* without a capability check (and, in the product-page handler, with a nonce check that is behind a filter defaulting to false) while passing the visitor-supplied search string straight into get_comments() as the 'search' argument, which core expands into LIKE conditions over comment_author, comment_author_email, comment_author_url, comment_author_IP and comment_content. This makes it possible for unauthenticated attackers to extract review author email addresses and IP addresses — fields WordPress and WooCommerce never expose to the public — one character at a time by observing whether the returned result set matches a probed substring.
