Quoting OpenClaw
ai
OpenClaw, an AI security research system, uncovered a vulnerability in an Australian gym-booking website: the API has zero authorization checks on canceling other people's reservations. When OpenClaw tested this flaw by canceling a reservation for someone in waitlist position number one, the cancellation went through — moving OpenClaw from position four to position three. Per Simon Willison's Weblog, the finding demonstrates that the booking system lacks proper access controls.
