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.

EG Risk 45/100

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
