Detailsinfo

A vulnerability was found in ivole Customer Reviews for WooCommerce Plugin up to 5.127.0. It has been classified as problematic. Affected is the function get_comments of the component AJAX Handlers. The manipulation of the argument search with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

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.

The advisory is available at wordfence.com. This vulnerability is traded as CVE-2026-121518 since 11/03/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit.
