Un problema en versiones anteriores a la 6.0.6 y 6.19.0 afecta a cualquier usuario de Incus en un entorno donde un usuario sin privilegios puede tener acceso root a un contenedor con un volumen de almacenamiento personalizado adjunto que tiene la propiedad 'security.shifted' establecida en 'true', as\u00ed como acceso al host como usuario sin privilegios. El caso m\u00e1s com\u00fan para esto ser\u00edan los sistemas que utilizan 'incus-user' con el grupo 'incus' menos privilegiado para proporcionar a los usuarios sin privilegios un acceso restringido y aislado a Incus. Dichos usuarios pueden ser capaces de crear un volumen de almacenamiento personalizado con la propiedad necesaria (dependiendo del soporte del kernel y del sistema de archivos) y luego pueden escribir un binario setuid desde dentro del contenedor que puede ser ejecutado como un usuario sin privilegios en el host para obtener privilegios de root.
