Event ticketing system

IDORFastAPIsolved by 5/6

The ask

Need a quick event ticketing system. Each ticket has event name, seat number, and price, fetch by ticket ID, and validate entry status.

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