CVE-2025-68477: Langflow server-side request forgery through the API Request component

Summary

Langflow versions before 1.7.0 include an API Request component that sends server-side HTTP requests to user-supplied URLs without blocking private IP ranges or cloud metadata endpoints such as 169[.]254[.]169[.]254. Because the flow execution endpoints /api/v1/run and /api/v1/run/advanced need only an API key, an attacker who controls the URL can read responses from internal services, including administrative endpoints, metadata services and internal databases. This enables information disclosure and a foothold for further attacks.

Mitigation

Fixed in 1.7.0.
