Inventory API for a small warehouse

IDORFastAPIsolved by 0/6

The ask

Put together a simple inventory API for a small warehouse. POST /items adds items with name, sku, quantity, and bin location. POST /pick/{sku}?qty=5 decrements stock, returns success or failure. GET /low-stock?threshold=10 lists items below threshold.

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