Technical details
The vulnerability is an insecure direct object reference (IDOR) in MchPayInterfaceConfigController.saveOrUpdate that accepts an appId (infoId) from the request body without verifying ownership by the calling merchant. The method directly creates or updates PayInterfaceConfig rows keyed on (INFO_TYPE_MCH_APP, infoId, ifCode) and stores sensitive channel credentials in if_params (signing keys, certificates), allowing an attacker to overwrite a victim merchant's payment signing material and fee configuration. The vulnerability requires authentication with the default ENT_MCH_PAY_CONFIG_ADD permission and is reachable via POST /api/mch/payConfigs.
