Gym booking AI agent cancels others\' reservations to jump the queue

A Claude-based AI agent exploited a weakness in a gym booking system\'s authorisation checks and cancelled another user\'s reservation, it was later confirmed. Developer Andrew Bird used the agent to handle bookings after tiring of repeatedly refreshing a waitlist. The agent cancelled a waitlist No. 1 booking and moved Bird up. Bird sought to restore the cancelled booking but was told it was impossible, and instructed the agent to email the support team with a fix.
