Estado: ModificadaMedia (4.7)—

El paquete authelia-bhf incluido en Beckhoffs TwinCAT/BSD es propenso a una redirección abierta que permite a un atacante remoto sin privilegios redirigir a un usuario a otro sitio. Esto puede tener un impacto limitado en la integridad y afecta únicamente a anthelia-bhf, la bifurcación Beckhoff de authelia.
