CVE-2026-35408
Directus is Missing Cross-Origin Opener Policy
Description
Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, Directus's Single Sign-On (SSO) login pages lacked a Cross-Origin-Opener-Policy (COOP) HTTP response header. Without this header, a malicious cross-origin window that opens the Directus login page retains the ability to access and manipulate the window object of that page. An attacker can exploit this to intercept and redirect the OAuth authorization flow to an attacker-controlled OAuth client, causing the victim to unknowingly grant access to their authentication provider account (e.g. Google, Discord). This vulnerability is fixed in 11.17.0.

Action Type Old Value New Value Added Translation Title: directus, Description: Directus es un panel de control de API y aplicaciones en tiempo real para gestionar contenido de bases de datos SQL. Antes de la versión 11.17.0, las páginas de inicio de sesión de Single Sign-On (SSO) de Directus carecían de un encabezado de respuesta HTTP Cross-Origin-Opener-Policy (COOP). Sin este encabezado, una ventana maliciosa de origen cruzado que abre la página de inicio de sesión de Directus conserva la capacidad de acceder y manipular el objeto de ventana de esa página. Un atacante puede explotar esto para interceptar y redirigir el flujo de autorización de OAuth a un cliente OAuth controlado por el atacante, haciendo que la víctima conceda acceso sin saberlo a su cuenta de proveedor de autenticación (p. ej., Google, Discord). Esta vulnerabilidad se corrigió en la versión 11.17.0. -
