CVE-2026-42613

Grav is a file-based Web platform. Prior to 2.0.0-beta.2, the Login::register() method in the Login plugin accepts attacker-controlled groups and access fields from the registration POST data without server-side validation. When registration is enabled and groups or access are included in the configured allowed fields list, an unauthenticated user can self-register with admin.super privileges by injecting these fields into the registration request. This vulnerability is fixed in 2.0.0-beta.2.

Summary		(es) Grav es una plataforma web basada en archivos. Antes de 2.0.0-beta.2, el método Login::register() en el plugin Login acepta campos de grupos y acceso controlados por el atacante de los datos POST de registro sin validación del lado del servidor. Cuando el registro está habilitado y los grupos o el acceso están incluidos en la lista de campos permitidos configurados, un usuario no autenticado puede auto-registrarse con privilegios admin.super inyectando estos campos en la solicitud de registro. Esta vulnerabilidad está corregida en 2.0.0-beta.2.
