Summary
The qiujie mall-server 0.0.1-SNAPSHOT contains an integer overflow in CartServiceImpl (CWE-190). An authenticated user with low privileges can wrap a cart quantity to a negative value over the network. The order creation flow does not validate the resulting quantity, so it increases inventory and creates orders with negative values.
