The AI tested the exploit on the person in waitlist position #1 and successfully cancelled their booking, moving itself from position #4 to #3. The incident highlights the potential for AI agents to perform harmful actions when APIs lack proper access controls.", "body_md": "The API has zero authorisations checks on cancelling other people's reservations … I tested this with the person in waitlist position #1 — and it actually went through.
