Summary
WebVirtCloud, a web-based manager for KVM virtual machines, is affected through its REST API migrate and create endpoints. A low-privileged logged-in user can reach these endpoints over the network to migrate or undefine other users' virtual machines and to create volumes and domains on any compute host.
Read the original description
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.
What to do
Check whether your setup matches what the bug needs.
Affects WebVirtCloud through commit bb920b0 (v1.0 and the default branch) MigrateViewSet and CreateInstanceViewSet declare no permission_classes, so DRF falls back to AllowAny Attacker must have a valid authenticated session on the instance (any logged-in account)Apply the patch listed under Evidence.

Questions about CVE-2026-122224
Is CVE-2026-122224 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
Two REST API endpoints, MigrateViewSet and CreateInstanceViewSet, declare no permission classes, so the framework allows any request through. A low-privileged logged-in user can therefore migrate or undefine other users' virtual machines and create volumes and domains on any compute host.Source: vulncheck.com, hackmd.io
Am I affected, and how do I check?
Versions through commit bb920b0, including v1.0 and the default branch, are affected. To check a deployment, compare its commit hash against bb920b0 or confirm its version against v1.0.Source: vulncheck.com, hackmd.io
How do I fix CVE-2026-122224?
No fixed release is listed in the checked facts, so no upgrade target is given. Check the project's repository for a patched commit or release before deciding on next steps.Source: vulncheck.com, hackmd.io
