Name of the Vulnerable Software and Affected Versions SoftwareX versions 4.18.0

Description A bug in the network handling of inventories was introduced, allowing players to request the server to drop more items than they had available. This led to a server crash and is believed to have been exploited. The issue did not cause duplication but resulted in a server crash.

Recommendations For version 4.18.0, update to version 4.18.1 or later, which includes the fix for this issue. As a temporary workaround, consider handling the InventoryTransactionPacket in the DataPacketReceiveEvent and verify that the item count dropped is not more than the available item count, although this is not recommended due to its complexity.
