CVE-2019-11711

Estado: ModificadaAlta (8.8)—

Cuando se reutiliza una ventana interior, no se considera el uso de document.domain para las protecciones de origen cruzado. Si las páginas en diferentes subdominios alguna vez usan cooperativamente document.domain, entonces cualquiera de las páginas puede abusar de esto para inyectar el script en páginas arbitrarias en el otro subdominio, incluso aquellas que no usaron document.domain para mitigar la seguridad de su origen. Esta vulnerabilidad afecta a Firefox ESR anterior a versión 60.8, Firefox anterior a versión 68 y Thunderbird anterior a versión 60.8.
