CVE-2026-33149

Estado: AnalizadaAlta (8.1)—

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Versions up to and including 2.5.3 set ALLOWED_HOSTS = '*' by default, which causes Django to accept any value in the HTTP Host header without validation. The application uses request.build_absolute_uri() to generate absolute URLs in multiple contexts, including invite link emails, API pagination, and OpenAPI schema generation. An attacker who can send requests to the application with a crafted Host header can manipulate all server-generated absolute URLs.

Leer descripción completaMostrar menos

The most critical impact is invite link poisoning: when an admin creates an invite and the application sends the invite email, the link points to the attacker's server instead of the real application. When the victim clicks the link, the invite token is sent to the attacker, who can then use it at the real application. As of time of publication, it is unknown if a patched version is available.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Requiere UI:R (interacción del usuario al hacer clic en enlace). Impactos: phishing (Host header envenenado), acceso a cuenta (token de invitación capturado), modificación de autenticación OAuth.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

      "value": "Tandoor Recipes es una aplicación para gestionar recetas, planificar comidas y crear listas de la compra. Las versiones hasta la 2.5.3 inclusive establecen ALLOWED_HOSTS = '*' por defecto, lo que provoca que Django acepte cualquier valor en la cabecera HTTP Host sin validación. La aplicación utiliza request.build_absolute_uri() para generar URLs absolutas en múltiples contextos, incluyendo correos electrónicos de enlaces de invitación, paginación de la API y generación de esquemas OpenAPI. Un atacante que pueda enviar solicitudes a la aplicación con una cabecera Host manipulada puede manipular todas las URLs absolutas generadas por el servidor. El impacto más crítico es el envenenamiento de enlaces de invitación: cuando un administrador crea una invitación y la aplicación envía el correo electrónico de invitación, el enlace apunta al servidor del atacante en lugar de a la aplicación real. Cuando la víctima hace clic en el enlace, el token de invitación se envía al atacante, quien luego puede usarlo en la aplicación real. En el momento de la publicación, se desconoce si hay una versión parcheada disponible."
