Impact
Due to a workaround for unmapped network items implemented in 4.0.0-BETA5 (8ac16345a3bc099b62c1f5cfbf3b736e621c3f76), arbitrary item IDs are able to be written into an item's NBT. The intended purpose of this is to make said unmapped network items able to be moved around the inventory without issues.
This led to an exploit due to internal limits on the range that item IDs can occupy (-32768 - 32767), while the tag type used to represent the replacement IDs for unknown items is a
TAG Int, allowing a range from -(2^31) - 2^31 - 1. This leads to an uncaught exception which crashes the server.Patches

Workarounds
In theory this can be checked by plugins using a custom
TypeConverter, but this is likely to be very cumbersome.For more information
