# CVE-2026-48751: Incus has a restricted project bypass leading to arbitrary command execution

Status: published. Published: 2026-08-21. Updated: 2026-11-05.

Incus is a system container and virtual machine manager. Prior to version 7.2.0, instance snapshots ignore the `restricted.containers.lowlevel=block` setting; allowing for arbitrary command execution on the Incus server by abusing lowlevel hooks such as `raw.lxc` and `raw.qemu`. Version 7.2.0 patches the issue.
