langflow is vulnerable to Server-Side Request Forgery (SSRF)
63
Medium Risk
This Affects:
langflowTL;DR
RSS Reader, SearXNG, Web Search, Home Assistant, Glean, and Docling Serve send HTTP requests to a URL taken from the flow, and the SSRF guard is either off by default or not used by those components. A signed-in user who can build a flow can point a component at a loopback, private, or metadata address and read the response. The fix checks each URL after DNS resolution, pins that address, and blocks private, loopback, link local, and metadata targets unless the host is allowlisted.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and signed-in users can run flows whose components fetch a URL.
