CVE-2018-12391

Estado: ModificadaAlta (8.8)—

Durante la reproducción de retransmisión en directo HTTP en Firefox para Android, los datos de audio son accesibles a través de orígenes que violan las políticas de seguridad. Debido a que este problema radica en el servicio Android subyacente, el fallo se aborda tratando todas las retransmisiones HLS como "cross-origin" y opacas para acceder. *Nota: este problema solo afecta a Firefox para Android. Las versiones de escritorio de Firefox no se ven afectadas.*. Esta vulnerabilidad afecta a las versiones anteriores a la 63 de Firefox, las versiones anteriores a la 60.3 de Firefox ESR y las versiones anteriores a la 60.3 de Thunderbird.
