{"apiVersion":"1.0","identifier":"CVE-2026-78205","description":"BentoML-s outbound connection safeguard (make_safe_connect in _internal/utils/uri.py) blocks private, loopback, and link-local IP addresses but fails to reject the RFC 6598 shared address space (100.64.0.0/10, CGNAT). In versions 1.4.19 through 1.4.39, an unauthenticated attacker can supply URLs pointing to that range via multipart file handling (MultipartSerde.ensure_file) or JSON request parsing (JSONSerde.parse_request), causing the server to make outbound requests to internal hosts on CGNAT networks (Server-Side Request Forgery). This is an incomplete fix for CVE-2025-54381.","publishedAt":"2026-08-24T01:16:57","lastModifiedAt":"2026-08-24T19:17:03","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-78205","cvssScore":5.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","epssProbability":0.003,"riskScore":0.6,"affectedProduct":"BentoML","affectedVersions":">=1.4.19,<=1.4.39","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-78205","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-78205","en":"https://www.redsauce.net/en/cves/CVE-2026-78205","fr":"https://www.redsauce.net/fr/cves/CVE-2026-78205","pt":"https://www.redsauce.net/pt/cves/CVE-2026-78205","de":"https://www.redsauce.net/de/cves/CVE-2026-78205","sk":"https://www.redsauce.net/sk/cves/CVE-2026-78205","el":"https://www.redsauce.net/el/cves/CVE-2026-78205"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-78205"}}
