Any unprivileged user could run machinectl to list every single containers running in the host even if the containers do not belong to this user (including containers belong to the root user), and access sensitive information associated with any individual container including its internal IP address, OS version, running processes, and file path for its rootfs. $ machinectl status cc8d10c7b9892b75843d200d54d34a3a cc8d10c7b9892b75843d200d54d34a3a(63633864313063376239383932623735) Since: Mon 2016-07-25 17:55:36 UTC; 34s ago Leader: 43494 (sleep) Service: docker; class container Root: /var/mnt/overlay/overlay/0429684e3da515ae4f11b8514c7b20f759613 Address: 172.17.0.2 fe80::42:acff:fe11:2 OS: Red Hat Enterprise Linux Server 7.2 (Maipo) Unit: docker-cc8d10c7b9892b75843d200d54d34a3a9435fe0f65527c254ebfd2d └─43494 sleep 3000 CAI Qian
