Impact
Due to a workaround applied in 1.13, an attacker may send a negative damage/meta value in a tool or armour item's NBT, which
TypeConverter then blindly uses as if it was valid without being checked.When this invalid metadata value reaches
Durable->setDamage(), an exception is thrown because the metadata is not within the expected range for damage values.This can be reproduced with either a too-large damage value, or a negative one.

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