      <title>CVE-2026-16144 — Kali Forms &lt;= 2.4.20 - Unauthenticated Remote Code Execution via 'thisPermalink' Field Parameter</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-16144</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; wpchill Kali Forms — Contact Form &amp;amp; Drag-and-Drop Builder&lt;/p&gt;
&lt;p&gt;The Kali Forms — Contact Form &amp;amp; Drag-and-Drop Builder plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.4.20 via the _save_data function. This is due to insufficient validation of the &amp;#39;thisPermalink&amp;#39; field value before it overwrites a trusted callable placeholder, allowing attacker-controlled strings to reach call_user_func() in _save_data(). This makes it possible for unauthenticated attackers to execute code on the server. Exploitation requires the target form to define a field with a name matching one of the reserved placeholder keys (&amp;#39;thisPermalink&amp;#39;, &amp;#39;entryCounter&amp;#39;, or &amp;#39;submission_link&amp;#39;), as check_if_placeholders_changed() only processes POST keys present in the form&amp;#39;s field_type_map.&lt;/p&gt;</description>
