### 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. ### Patches c8e1cfcbee4945fd4b63d2a7e96025c59744d4f1 ### Workarounds In theory this can be checked by plugins using a custom `TypeConverter`, but this is likely to be very cumbersome. ### For more information * Email us at [team@pmmp.io](mailto:team@pmmp.io)
