# CVE-2026-73297

> 6.9 MEDIUM · 🧪 PoC

## Beschreibung

Microsoft UFO open-source framework for intelligent automation across devices and platforms. Prior to 3.0.8, _is_blocked_ip in ufo/utils/url_security.py did not block NAT64 prefixes 64:ff9b::/96 and 64:ff9b:1::/48, the 6to4 prefix 2002::/16, or the Teredo prefix 2001::/32 and did not re-check embedded IPv4 destinations, allowing an unauthenticated remote attacker who can influence URLs processed by validate_url to bypass the SSRF guard and reach cloud metadata, internal services, or localhost. This issue is fixed in version 3.0.8.
