Technical description

A horizontal privilege escalation vulnerability exists in x-ui 0.3.2. An authenticated user can modify the inbound proxy configurations of other users, including remark, port, protocol, settings, enabled state, expiry time and traffic quota, by submitting a request referencing the target resource identifier. The update path fails to verify that the target resource belongs to the requesting session user, allowing unauthorized cross-user modification of data.
