Kerentanan Improper Link Resolution Before File Access ('Link Following'). Skor CVSS 3.1 9.9 (Critical) menurut github.com.

Deskripsi (NVD)

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.
