- The notification receiver section documents an inbound callback interface with signed parameters but does not explicitly instruct implementers to verify the Alipay signature, validate app_id/msg_method, and reject invalid or replayed notifications before processing. Integrators may therefore accept forged callbacks, causing unauthorized state changes, false success/failure handling, or fraudulent merchant workflow actions.
