CVE-2026-46414: CWE-290: Authentication Bypass by Spoofing in microsoft UFO
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.
AI Analysis
Technical Summary
Microsoft UFO 3.0.1-4-ge2626659 contains an authentication bypass vulnerability where the WebSocket control plane improperly trusts client-supplied identity and role information in task messages. An authenticated WebSocket client with the shared server token can claim a higher-privilege role ('constellation') and specify a victim device ID, causing the server to accept and execute attacker-controlled tasks on that device. The client registry also permits duplicate client_id registrations, overwriting live client data and enabling hijacking of task protocols. This results in role and identity spoofing and unauthorized peer task control.
Potential Impact
An attacker with authenticated WebSocket access and the shared server token can impersonate higher-privilege roles and dispatch malicious tasks to other connected devices. This can lead to full compromise of targeted devices, including confidentiality, integrity, and availability impacts. The vulnerability allows task hijacking and unauthorized control within the Microsoft UFO framework.
Mitigation Recommendations
No official patch or remediation has been published yet. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the shared server token and WebSocket interfaces to trusted clients only. Monitor for unusual task dispatch behavior and consider isolating affected versions from sensitive environments.
