      <title>CVE-2026-56393 — Craft CMS - Multiple Stored Cross-Site Scripting in Settings Names and Field Options</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-56393</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; craftcms cms&lt;/p&gt;
&lt;p&gt;Craft CMS 4.x (&amp;gt;= 4.0.0-RC1, &amp;lt; 4.17.0-beta.1) and 5.x (&amp;gt;= 5.0.0-RC1, &amp;lt; 5.9.0-beta.1) contain multiple stored cross-site scripting vulnerabilities where settings names and field option labels are rendered without sanitization (e.g., via the checkbox.twig template, which used {{ label|raw }}). An authenticated administrator (with allowAdminChanges enabled) can inject malicious payloads into section names, volume names, user group names, global set names, generated field names, checkbox/radio option labels, and custom source labels, causing arbitrary JavaScript to execute in other users&amp;#39; control-panel sessions. Fixed in 4.17.0-beta.1 and 5.9.0-beta.1.&lt;/p&gt;</description>
