CVE-2026-43934

e107 is a content management system (CMS). Prior to 2.3.4, a Broken Access Control vulnerability exists in the application, allowing an unauthorized authenticated user to edit comments posted by others. This stems from inadequate server-side access control validation, where the application depends only on a predictable identifier in the request to determine which comment to edit, without confirming the requesting user’s ownership of the comment. This vulnerability is fixed in 2.3.4.

Summary		(es) e107 es un sistema de gestión de contenido (CMS). Antes de la versión 2.3.4, existe una vulnerabilidad de Control de Acceso Roto en la aplicación, permitiendo a un usuario autenticado no autorizado editar comentarios publicados por otros. Esto se deriva de una validación de control de acceso inadecuada del lado del servidor, donde la aplicación depende solo de un identificador predecible en la solicitud para determinar qué comentario editar, sin confirmar la propiedad del comentario por parte del usuario solicitante. Esta vulnerabilidad está corregida en la versión 2.3.4.
