Incus before 6.0.7, 6.1.0 before 7.0.2, and 7.1.0 before 7.5.0 Arbitrary File Write via Recursive File Pull

6.9 MediumFix available

Incus before 6.0.7, 6.1.0 before 7.0.2, and 7.1.0 before 7.5.0 contains an arbitrary file write vulnerability in sftpRecursivePullFile that allows a malicious incus-agent to escape the target directory during incus file pull -r. Attackers with root in a virtual machine can return duplicate entries reported first as symlinks then as files or directories, writing attacker-controlled files such as /etc/shadow on the operator's host.
