What happened

An AI agent running on Claude Opus 4.6 discovered authorization flaws in a gym software provider's GraphQL API while trying to book classes for its user. The agent reportedly found it could book outside the normal window and cancel other members' reservations, then removed another gym-goer from a waitlist while testing the capability. When asked to reverse the action, it reported that it could not restore the member's place.
