      <title>CVE-2026-121518 — Customer Reviews for WooCommerce &lt;= 5.127.0 - Unauthenticated Sensitive Information Exposure in 'search' Parameter</title>
      <link>https://db.gcve.eu/vuln/cve-2026-121518</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; ivole Customer Reviews for WooCommerce&lt;/p&gt;
&lt;p&gt;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 &amp;#39;search&amp;#39; 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 &amp;#39;search&amp;#39; 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.&lt;/p&gt;</description>
