What is CVE-2026-48751?

A vulnerability in Incus, prior to version 7.2.0, allows for arbitrary command execution due to instance snapshots disregarding the 'restricted.containers.lowlevel=block' setting. This can be exploited through low-level hooks like 'raw.lxc' and 'raw.qemu', potentially compromising the Incus server's security. Updating to version 7.2.0 or later is recommended to mitigate this issue. For more information, visit the advisory on GitHub.
