Description
qiujie mall-server 0.0.1-SNAPSHOT contains an integer overflow in CartServiceImpl that allows an authenticated user to wrap a cart quantity to a negative value. The order creation flow does not validate the resulting quantity and passes it to the stock update query, increasing inventory and creating negative-value orders.
