Descriptions

Decidim is a participatory democracy framework. Starting in version 0.23.0 and prior to versions 0.27.5 and 0.28.0, the CSRF authenticity token check is disabled for the questionnaire templates preview. The issue does not imply a serious security thread as you need to have access also to the session cookie in order to see this resource. This URL does not allow modifying the resource but it may allow attackers to gain access to information which was not meant to be public. The issue is fixed in version 0.27.5 and 0.28.0. As a workaround, disable the templates functionality or remove all available templates.

Decidim es un framework de democracia participativa. A partir de la versión 0.23.0 y anteriores a las versiones 0.27.5 y 0.28.0, la verificación del token de autenticidad CSRF está deshabilitada para la vista previa de las plantillas de cuestionario. El problema no implica un problema de seguridad grave, ya que también es necesario tener acceso a la cookie de sesión para poder ver este recurso. Esta URL no permite modificar el recurso, pero puede permitir a los atacantes obtener acceso a información que no estaba destinada a ser pública. El problema se solucionó en las versiones 0.27.5 y 0.28.0. Como workaround, desactive la funcionalidad de plantillas o elimine todas las plantillas disponibles.
