CVE-2023-6868

Estado: ModificadaMedia (4.3)—

En algunos casos, el agente de usuario permitiría solicitudes de inserción que carecían de un VAPID válido aunque la suscripción del administrador de inserción definiera uno. Esto podría permitir que se envíen mensajes vacíos desde partes no autorizadas. *Este error solo afecta a Firefox en Android.* Esta vulnerabilidad afecta a Firefox < 121.
