Internal resource disclosure via unrestricted server-side requests
Published Dec 19, 2025 · Updated Dec 19, 2025
SSRF in Langflow before 1.7.0 allows remote authenticated users to read internal HTTP resources through crafted flow URLs. The API Request component only normalizes and format-checks a user-controlled URL before httpx sends it server-side, then places the response body in flow output. An API key and control of the component URL in an executable flow are required; exposed metadata and administrative services can disclose credentials and configuration.
