CVE-2026-121518
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 crshowmoreallreviews and crshowmorereviews AJAX actions. This is due to the handlers being hooked on wpajaxnopriv 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 getcomments() as the 'search' argument, which core expands into LIKE conditions over commentauthor, commentauthoremail, commentauthorurl, commentauthorIP and commentcontent. 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.
