CVE-2015-7184

Estado: ModificadaMedia (6.8)—

La implementación de la API fetch en Mozilla Firefox en versiones anteriores a 41.0.2 no restringe el acceso al cuerpo de respuesta de HTTP en ciertas situaciones, donde las credenciales de usuario son suministradas pero el algoritmo de petición de orígenes cruzados CORS se sigue indebidamente, lo que permite a atacantes remotos eludir la Same Origin Policy a través de un sitio web manipulado.
