CVE-2026-69087

The Grav form plugin (getgrav/grav-plugin-form) before 9.1.13 contains an open redirect vulnerability. Since v9.1.11, the redirect process action evaluates user-supplied form data inside Twig expressions, and Grav::redirect() accepts external URLs without origin validation. When a form blueprint defines a redirect target such as redirect: "{{ form.value('next') }}" using an attacker-controllable field, an unauthenticated form submitter can supply a value like https://evil.com to cause a 302 redirect to an arbitrary external site, enabling phishing.

Summary		(es) El plugin de formulario de Grav (getgrav/grav-plugin-form) anterior a la versión 9.1.13 contiene una vulnerabilidad de redirección abierta. Desde la v9.1.11, la acción de proceso de redirección evalúa los datos de formulario proporcionados por el usuario dentro de expresiones Twig, y Grav::redirect() acepta URL externas sin validación de origen. Cuando un esquema de formulario define un objetivo de redirección como redirect: ’{{ form.value(’next’) }}’ utilizando un campo controlable por el atacante, un remitente de formulario no autenticado puede proporcionar un valor como https://evil.com para causar una redirección 302 a un sitio externo arbitrario, lo que permite el phishing.
