Este problema permitía que, cuando un administrador de instancia bloqueaba la disponibilidad de Duo de un grupo, un usuario autenticado con permisos de Propietario de grupo pudiera haber vuelto a habilitar la salida de datos respaldada por IA a un servicio de terceros para ese grupo y sus proyectos descendientes, debido a la granularidad insuficiente de los controles de aplicación del bloqueo de administrador."
