CVE-2026-105790: SSRF (CVSS 6.4)

Description

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.
