      <title>CVE-2026-15941 — Relevanssi &lt;= 4.27.1 and Relevanssi Premium &lt;= 2.30.2 - Authenticated (Contributor+) SQL Injection</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-15941</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Relevanssi Premium – A Better Search, comesio Relevanssi – A Better Search&lt;/p&gt;
&lt;p&gt;The plugin provides an Admin Search page that allows users with the `edit_posts` capability to run Relevanssi searches from the WordPress dashboard. The AJAX handler accepts a URL-encoded `args` parameter, parses it into a `WP_Query`, and then passes user-controlled taxonomy query data into Relevanssi&amp;#39;s taxonomy restriction builder. The taxonomy value is sanitized as text but is not parameterized for SQL before being interpolated into a term taxonomy lookup query. This allows an authenticated contributor-level attacker to inject SQL through the Admin Search AJAX request and execute time-based blind SQL injection against the WordPress database.&lt;/p&gt;</description>
