CVE-2019-11725

Estado: ModificadaMedia (6.5)—

Cuando un usuario navega hacia un sitio marcado como no seguro por la API Safebrowsing, se muestran mensajes de advertencia y se interrumpe la navegación, pero los recursos del mismo sitio cargados por medio de websockets no se bloquean, lo que conlleva a la carga de recursos no seguros y evita las protecciones de seguridad. Esta vulnerabilidad afecta a Firefox anterior a versión 68.
