Doc Text:
A flaw was found in WebVirtCloud. Missing access controls on virtual machine management endpoints allow authenticated low-privileged users to manipulate or delete virtual machines belonging to other users. By submitting requests directly to unprotected REST API (Application Programming Interface) migration and instance creation endpoints, an attacker can disrupt existing virtual machines and provision unauthorized storage volumes and domains across compute hosts.

Description OSIDB Bzimport 2026-11-05 22:30:47 UTC 
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.
