      <title>CVE-2026-56736 — phpMyFAQ has Stored XSS in Admin FAQ Editor via HTML Entity Bypass in Frontend FAQ Submission</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-56736</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; thorsten phpMyFAQ&lt;/p&gt;
&lt;p&gt;phpMyFAQ is an open source FAQ web application. A stored cross-site scripting (XSS) vulnerability in versions prior to 4.2.0-alpha allows any unauthenticated user (or low-privileged registered user) to inject arbitrary JavaScript that executes in an administrator&amp;#39;s browser when they review or edit a user-submitted FAQ entry. This leads to admin account takeover via session theft. The vulnerability exists because `html_entity_decode()` converts HTML entities into executable HTML after `strip_tags()` has already passed them through, and the admin template renders the content with Twig&amp;#39;s `|raw` filter without any output sanitization. Version 4.2.0-alpha fixes the issue.&lt;/p&gt;</description>
