Microsoft has now urged all users of Minecraft Java Edition to update their games to remove this vulnerability. Players are urged to close all instances of Minecraft and update their game launcher. Modified Minecraft clients may not update themselves automatically.

Operators of Minecraft servers have additionally been asked to update their servers or take other measures to secure their servers. If this is not possible, other workarounds can be used to secure your Minecraft server.

This vulnerability poses a potential risk of your computer being compromised, and while this exploit has been addressed with all versions of the game client patched, you still need to take the following steps to secure your game and your servers.
