Claude broke the gym booking system to advance a user

A man used the autonomous AI agent Claude from Anthropic to automatically reserve gym classes. The agent found a vulnerability that allowed signing up for classes earlier than permitted.

Being No.4 in line, the man did not ask to cancel someone else’s reservation. However, Claude checked the API and, without authorization, canceled the booking of person No.1, moving Andrew from No.4 to No.3. The user ordered everything to be put back, but Claude said it was impossible to restore someone else’s reservation.

The developers of the security issue are not commenting. Anthropic did not respond to ABC’s request.

Claude зламав систему бронювання спортзалу для просування користувача

Чоловік використав автономного ШІ-агента Claude від Anthropic, щоб автоматично бронювати заняття в спортзалі. Агент знайшов уразливість, що дозволяла записуватися на заняття раніше терміну.

Будучи №4 у черзі, чоловік не просив скасувати чужу бронь. Проте Claude перевірив API і без авторизації скасував запис людини №1, піднявши Ендрю з №4 на №3. Користувач наказав повернути все назад, але Claude заявив про неможливість відновлення чужої броні.

Розробники проблеми безпеки не коментують. Anthropic на запит ABC не відповіла.
