Langflow instance exposed to the internet

published 2026-08-05 · updated 2026-08-05

Why it matters

Your Langflow UI is reachable from the internet. Flows, stored credentials and model API keys sit behind it, and older versions have unauthenticated remote-code-execution vulnerabilities that bots exploit within hours of disclosure.

What a probe sees

GET :7860/api/v1/version or /health answers Langflow JSON without login.

Internet-facing exposure — observable from the public internet with GET-only probes (the same probes unauth.dev sends).

In the wild

No honeypot telemetry for this service yet (in_the_wild: null in the dataset). We do not invent numbers. The block appears when the honeypot has real data.
