    Title
    WebVirtCloud through commit bb920b0 Missing Authorization in REST API Migrate and Create Endpoints
    Summary
    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.

    Title
    WebVirtCloud Missing Authorization on Instance Control Actions
    Summary
    WebVirtCloud fails to properly validate permission flags in UserInstance grants, allowing view-only users to perform privileged actions. Attackers with read-only grants can power off virtual machines, reset root passwords, install SSH keys, and manage ISO images by exploiting the get_instance gate that only checks grant existence.

    Title
    WebVirtCloud through commit bb920b0 Missing Authorization in REST API Migrate and Create Endpoints
    Summary
    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.

    CVE-2026-92761 (GCVE-0-2026-92761)

    Title
    WebVirtCloud Missing Authorization on Instance Control Actions
    Summary
    WebVirtCloud fails to properly validate permission flags in UserInstance grants, allowing view-only users to perform privileged actions. Attackers with read-only grants can power off virtual machines, reset root passwords, install SSH keys, and manage ISO images by exploiting the get_instance gate that only checks grant existence.
