Internal response disclosure via unvalidated Invoke URL

Published Aug 18, 2026 · Updated Aug 18, 2026

Server-side request forgery in the agent Invoke component in InfiniFlow RAGFlow before 0.26.3 allows remote authenticated users to read internal HTTP responses. In agent/component/invoke.py, _build_url resolves canvas and runtime template variables into a destination URL and _invoke sends it through requests without calling the shared assert_url_is_safe guard or pinning the resolved address before returning response text as component output. Any user who can create or trigger an agent can target loopback, link-local, RFC 1918, or cloud metadata endpoints, and an agent that interpolates {sys.query} into the URL lets any chat user who can run that agent choose the destination.
