CVE-2026-85686Public exploitNetwork attack vectorHinoki check available

Unauthenticated SSRF via unvalidated multimodal media URLs

Published Sep 4, 2026 · Updated Sep 4, 2026

SSRF in ModelScope ms-swift 4.5.2 and earlier allows remote attackers to read internal resources through crafted multimodal media URLs. The swift/template/vision_utils.py load_file function passes any HTTP(S) media path to session.get without destination validation and follows redirects. A network-reachable swift deploy multimodal API is sufficient because its default bind address exposes the service and api_key=None disables authentication; returned media can disclose internal services or cloud metadata.
