Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Microsoft UFO open-source framework for intelligent automation across devices and platforms. In 3.0.1-4-ge2626659, Microsoft UFO's WebSocket control plane trusts client-supplied identity and role fields in task messages. A client connection can register as a normal device, but later send a TASK message claiming client_type="constellation" and target_id=<victim-device-id>. The server trusts the role and target values from the wire message rather than enforcing the role registered for that WebSocket connection. As a result, any authenticated WebSocket client with the shared server token can spoof the higher-privilege constellation role and dispatch attacker-controlled tasks to another connected device. The same client registry also allows duplicate client_id registration, overwriting an existing live client's stored websocket, role, and task protocol. This is an authenticated WebSocket role/identity spoofing issue leading to peer task hijacking.
