Severity: critical · CVSS 9.9 · Published 2026-11-06

LXD is a container management system that enforces project restrictions to prevent privileged operations. An attacker can bypass these restrictions by creating a malicious container snapshot in an unrestricted project, then moving it to a restricted project and restoring it. This allows arbitrary command execution with root privileges on the host system.

Technical details

Instance snapshots ignore the restricted.containers.lowlevel=block project setting, permitting abuse of lowlevel hooks such as raw.lxc and raw.qemu to achieve arbitrary command execution. An attacker crafts a snapshot in an unrestricted project with embedded hook commands, transfers it to a restricted project, and restores it to execute those commands as root. The vulnerability stems from insufficient enforcement of project restrictions during snapshot restore operations.
