CVE-2026-6617Public exploitNetwork attack vector

Authenticated SSRF via direct remote-schema fetch

Published Apr 20, 2026 · Updated Apr 20, 2026

SSRF in LangGenius Dify 0.6.0 through 0.6.9 allows remote authenticated users to issue server-side GET requests via a crafted schema URL. ApiToolManageService.get_api_tool_provider_remote_schema passes the user-controlled url directly to httpx.get instead of the SSRF proxy. Low-privileged account access is required; response differences disclose internal port status and can expose metadata or trigger GET-based internal actions.
