Order-workflow manipulation via zero-default quantity lookup
Published Aug 7, 2026 · Updated Aug 7, 2026
Behavioral workflow weakness in WonderTrader 0.9.9 and earlier allows remote authenticated users to influence pending-order handling. TraderAdapter::getUndoneQty searches _undone_qty with a caller-supplied instrument code and returns zero when the key is absent, conflating an unknown instrument with no pending quantity. Public records identify no network entry point or concrete state transition; the documented consequence is limited to order-processing integrity.
