CVE-2026-121518

Customer Reviews for WooCommerce <= 5.127.0 - Unauthenticated Sensitive Information Exposure in 'search' Parameter

Published Nov 13, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
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.
