Summary
Jeepay through 3.2.9 contains an insecure direct object reference vulnerability that allows authenticated merchant users to overwrite another merchant application's payment channel configuration by supplying a victim infoId to MchPayInterfaceConfigController.saveOrUpdate. Attackers holding the default ENT_MCH_PAY_CONFIG_ADD permission can replace signing keys, certificates, and fee rates to break or redirect the victim merchant's payment processing.
