WebVirtCloud through commit bb920b0 contains a missing authorization vulnerability that allows low-privileged authenticated users to reach MigrateViewSet and CreateInstanceViewSet because no permission_classes are declared, so Django REST Framework defaults to AllowAny. Attackers can send requests to /api/v1/migrate/ or the compute instance create endpoint to migrate or undefine other users' virtual machines and create volumes and domains on any compute host.
