Marketplace API for selling digital art

IDORFastAPIsolved by 0/6

The ask

Give me a marketplace API for selling digital art. Listings have a title, price, and image URL; buyers can fetch by listing ID and leave reviews with ratings.

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