CVE-2026-73297

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.

Summary		(es) Microsoft UFO framework de código abierto para automatización inteligente en dispositivos y plataformas. Antes de la versión 3.0.8, _is_blocked_ip en ufo/utils/url_security.py no bloqueaba los prefijos NAT64 64:ff9b::/96 y 64:ff9b:1::/48, el prefijo 6to4 2002::/16, o el prefijo Teredo 2001::/32 y no volvía a verificar los destinos IPv4 incrustados, permitiendo a un atacante remoto no autenticado que puede influir en las URL procesadas por validate_url eludir la protección SSRF y alcanzar metadatos de la nube, servicios internos o localhost. Este problema está solucionado en la versión 3.0.8.
