CVE-2024-1550

Estado: ModificadaMedia (6.1)—

Un sitio web malicioso podría haber utilizado una combinación de salir del modo de pantalla completa y `requestPointerLock` para provocar que el mouse del usuario se reposicionara inesperadamente, lo que podría haber llevado a confusión al usuario y haber otorgado permisos sin darse cuenta que no tenía intención de otorgar. Esta vulnerabilidad afecta a Firefox < 123, Firefox ESR < 115.8 y Thunderbird < 115.8.
