GHSA-WQQV-JCFR-9F5G PocketMine-MP has improperly handled dye colour IDs in banner NBT, leading to server crash

Impact DyeColorIdMap-fromId did not account for the possibility that it might be given invalid input. This means that an undefined offset error would occur whenever this happened. This code is indirectly called during Banner-deserializeCompoundTag, which is invoked when deserializing any item NBT...

Improperly checked IDs on itemstacks received from the client leading to server crash in PocketMine-MP

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 withou...

Insufficient type validation in pocketmine/pocketmine-mp

Impact When an inventory interaction is performed e.g. moving an item around an inventory, the client sends a serialized version of the itemstack to the server, which the server then deserializes and compares against its own copy. If the copies don't match, the transaction is invalid. This involv...

Improperly checked metadata on tools/armour itemstacks received from the client

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...

Uncapped length of skin data fields submitted by players

Impact Some skin data fields e.g. skinID, geometryName are not capped in length. These fields are typically saved in the NBT data of a player when the player quits the server, or during an autosave. This is problematic due to the 32767 byte limit on TAGStrings. If any of these fields exceeds 3276...

Impact Players can fill book pages with as many characters as they like; the server does not check this. In addition, the maximum of 50 pages is also not enforced, meaning that players can create "book bombs". This causes a variety of problems: - Oversized NBT on the wire costing excess bandwidth...
