LM Studio local API reachable without authentication

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

Why it matters

LM Studio's OpenAI-compatible API is meant for localhost. On the public internet, strangers can list and run your local models on your hardware.

What a probe sees

GET :1234/api/v0/models answers the LM Studio local API without auth.

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.
