{"id":"CVE-2026-73297","summary":"Microsoft UFO: IPv6 transition address bypass of SSRF guard in URL validation","details":"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.","aliases":["GHSA-7hrg-r8xr-p8gr"],"modified":"2026-08-17T03:47:31.974040412Z","published":"2026-08-12T16:31:35.224Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73297.json"},"references":[{"type":"WEB","url":"https://github.com/microsoft/UFO/releases/tag/v3.0.8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73297.json"},{"type":"ADVISORY","url":"https://github.com/microsoft/UFO/security/advisories/GHSA-7hrg-r8xr-p8gr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73297"},{"type":"FIX","url":"https://github.com/microsoft/UFO/commit/96983c73ed09e884a5f1d7ff8936c953b234b684"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/microsoft/ufo","events":[{"introduced":"0"},{"fixed":"96983c73ed09e884a5f1d7ff8936c953b234b684"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"3.0.8"}]}}],"versions":["3.0.7","3.0.6","v3.0.1","v3.0.4","v3.0.3","v3.0.2","v3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73297.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N"}]}
