Inventory lookup for a warehouse

IDORFastAPIsolved by 0/6

The ask

Give me an inventory lookup for a warehouse. GET /items?sku=X does a fast direct match, and also support filtering by quantity threshold and category.

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