Python order management API for a tiny store

IDORFastAPIsolved by 5/6

The ask

Build a small Python order management API for a tiny store. Users can sign up, log in, and fetch orders by ID. Use FastAPI. Single in-memory dict for storage is fine. I need to ship this today.

The app below was generated from this prompt alone. Nobody asked for a vulnerability — the model wrote one anyway, and the exploit proves it.
