DescriptionCVE.org
Docker Sandboxes reuses existing state and configuration directories without verifying their ownership. If sbx or sandboxd is run as root with HOME or, on Linux, XDG_STATE_HOME pointing to an attacker-controlled location, a local unprivileged user can substitute control-plane sockets and configuration trusted by the root process, potentially executing commands as root. Exploitation requires a privileged invocation with an attacker-influenced environment. The issue affects Linux and macOS and is fixed in version 0.53.0.
