CVE-2025-10216Network attack vector

Order integrity loss via voucher confirmation race

Published Sep 10, 2025 · Updated Sep 11, 2025

Race condition in GrandNode 2.0 through 2.3.0 allows remote authenticated users to alter order integrity via concurrent voucher submissions. Public records identify the ConfirmOrder voucher handler and giftvouchercouponcode input but do not disclose the shared resource or missing synchronization operation. Exploitation requires low-privileged authentication, user interaction, and difficult timing; the documented consequence is limited to unauthorized data modification.
