Summary
Incus vulnerable to root RCE via image backup.yaml symlink
Details

Incus is a system container and virtual machine manager. Prior to version 7.3.0, an unprivileged, project-confined Incus user (a non-admin TLS/RBAC identity with can_create_images and can_create_instances) can execute arbitrary code as root on the host. A crafted image ships backup.yaml as a symlink to a host file. When the root daemon writes the instance's backup file, it follows the symlink. Version 7.3.0 patches the issue.
