CVE-2026-46414: CWE-290: Authentication Bypass by Spoofing in microsoft UFO
CVE-2026-46414 is an authentication bypass vulnerability in Microsoft UFO version 3. 0. 1-4-ge2626659. The issue arises because the WebSocket control plane trusts client-supplied identity and role fields in task messages, allowing an authenticated client to spoof higher-privilege roles and send tasks to other devices. Additionally, duplicate client_id registration can overwrite existing client connections, enabling task hijacking. This vulnerability leads to unauthorized task dispatch and potential control over connected devices.
AI Analysis
Technical Summary
Microsoft UFO's WebSocket control plane in version 3.0.1-4-ge2626659 does not enforce the role registered for a WebSocket connection but instead trusts the client-supplied role and target_id fields in task messages. An authenticated client with the shared server token can spoof the 'constellation' role and target other devices, dispatching attacker-controlled tasks. The client registry also permits duplicate client_id registration, overwriting live client data and enabling task protocol hijacking. This is an authentication bypass by spoofing vulnerability classified under CWE-290, CWE-639, and CWE-862.
Potential Impact
An attacker with authenticated WebSocket access and the shared server token can impersonate higher-privilege roles and send malicious tasks to other connected devices, potentially compromising confidentiality, integrity, and availability of those devices. The vulnerability allows peer task hijacking and unauthorized control within the network of devices using Microsoft UFO.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been published at this time. Until a patch is available, restrict access to the shared server token and limit WebSocket client authentication to trusted entities only.
