Detailsinfo

A vulnerability was found in Microsoft UFO up to 3.0.8 and classified as problematic. This issue affects the function websockets.connect of the file aip/transport/websocket.py of the component WebSocket Transport. The manipulation with an unknown input leads to a cross-domain policy vulnerability. Using CWE to declare the problem leads to CWE-942. The product uses a cross-domain policy file that includes domains that should not be trusted. Impacted is confidentiality. The summary by CVE is:

Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. Prior to 3.0.9, authenticated device registration through /api/devices can supply a permitted attacker-controlled WebSocket endpoint while aip/transport/websocket.py applies pinned_addresses only to the initial destination. The pinned websockets.connect() client follows cross-origin redirects and opens a new TCP connection before Galaxy performs its post-handshake peer-IP validation, allowing WebSocket upgrade requests to internal hosts reachable from the server. The confirmed impact is the internal connection and handshake request, and does not establish arbitrary HTTP methods, response-body disclosure, a completed AIP session, or cloud metadata access. This issue is fixed in version 3.0.9.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-105790 since 10/05/2026. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 10/06/2026).
