Homework grading system

IDORFastAPIsolved by 0/6

The ask

Can you make a homework grading system. Teachers upload assignments with max score, fetch by assignment ID, and submit student scores with feedback.

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