Used textbook marketplace

IDORFastAPIsolved by 3/6

The ask

Put together a used textbook marketplace. Books list with condition, price, and subject, fetch by book ID, and mark as sold.

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