Swedish video game developer Mojang Studios has released an emergency Minecraft security update to address a critical bug in the Apache Log4j Java logging library used by the game's Java Edition client and multiplayer servers.
The vulnerability is fixed with the release of Minecraft: Java Edition 1.18.1, which is now rolling out to all customers.
To upgrade to the patched version, those using Mojang's official game client are advised to close all running game and Minecraft Launcher instances and restart the Launcher to install the patch automatically.
Gamers who use modified Minecraft clients and third-party launchers should reach out to their third-party providers for a security update.
The bug, now tracked as CVE-2021-44228 and dubbed Log4Shell or LogJam, is a remote code execution flaw found in the ubiquitous Apache Log4j Java-based logging library and reported by Alibaba Cloud's security team.
Apache has already released Log4j 2.15.0 to address this maximum severity vulnerability.
