      <title>CVE-2026-53654 — Grav: Unauthenticated open redirect via login twofa_cancel _redirect</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-53654</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; getgrav grav&lt;/p&gt;
&lt;p&gt;Grav is a file-based Web platform. Prior to 3.8.5, the Login plugin twofa_cancel task accepts a client-controlled _redirect field without a nonce and allows an unauthenticated request to set an external http, https, or protocol-relative Location target. Controller::execute() applies the field when taskTwofa_cancel() sets no redirect, and Grav::getRedirectResponse() accepts the target through Uri::isExternal(), enabling phishing redirects from a trusted Grav host. This issue is fixed in version 3.8.5.&lt;/p&gt;</description>
