HUIZHI ChargeOS cloud through 3.0.9 contains an insecure direct object reference vulnerability in the hcp-mp MeController and OrderController that trusts client-supplied userId, openId and orderNumber parameters. Attackers can enumerate sequential member ids against endpoints like /me/getMemberBalanceByUserId and /order/orderDetail to read any member's wallet, credit, profile and charging orders.
