CVE-2018-5181

Estado: ModificadaAlta (7.5)—

Si una URL que utiliza el protocolo "file:" es arrastrada y soltada en una pestaña abierta que se está ejecutando en un proceso hijo diferente, la pestaña abrirá un archivo local correspondiente a la URL soltada, algo que va en contra de la política. Una forma de hacer que la pestaña de destino se abra de forma más fiable en un proceso separado es abrirla con la palabra clave "noopener". Esta vulnerabilidad afecta a las versiones anteriores a la 60 de Firefox.
