Why this priority: High severity, with no exploitation signal yet.

Published 4 Nov 2026 · Updated 9 Nov 2026 · NVD status: Deferred

What it is

An action never checks whether the caller is allowed to perform it.

How it is reached

An attacker can exploit it over the network, with an ordinary user account, and nobody has to click anything.

What an attacker gains

A successful attack can change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker reach data or actions their role should not allow.

Is it being exploited?

There is no public report of exploitation yet. EPSS estimates a 0.33% chance of exploitation activity in the next 30 days, higher than 27% of scored CVEs.

What to do

No fixed version is listed yet. Find every place retspen webvirtcloud runs, watch the references for a fix, and plan a replacement if it is no longer supported.
While there is no fix, review who holds accounts that can reach it.

Description from NVD

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 this means for your architecture.

A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.

Components it touches

Permission checks in APIs and admin surfaces. The flaw sits between one role or tenant and another.
Multi-tenant services. The flaw sits between one role or tenant and another.

Trust boundaries in play

Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
Between one role or tenant and another. An attacker who crosses it can reach data or actions their role should not allow.
