CVE-2026-9493Network attack vector

Cross-account order disclosure via user-controlled query key

Published May 29, 2026 · Updated May 29, 2026

Insecure direct object reference in BankPro Service Center allows remote authenticated users to read other users' EC order details. A specific query function uses a user-controlled object key without enforcing ownership, so changing the request parameter selects another user's order. A valid account and network access are required; the reported effect is cross-account order disclosure, with no reported write or service-interruption capability.
