Other editions with a version "1.18.1":
 

1.18.1 is a minor update to Java Edition, released on December 10, 2021, which makes minor changes related to fog and fixes bugs.[1] It is compatible with 1.18 servers.

Most importantly, this version fixes a critical security vulnerability in the Log4j library of the dedicated server release that could be used to perform a remote code execution exploit. As a result, players were urged to secure their clients and servers.[2] This is the final version released in 2021.

While this wasn’t the last update to 1.18, it was the last before the development versions of 1.19 started.

Changes

General

Fog

  • World fog now starts farther away from the player, to make distant terrain more visible.
  • Instead of applying fog as a spherical volume, it is now applied as a cylindrical volume.

Fixes

8 issues fixed

From released versions before 1.18

  • MC-152198 – Actual render distance is 2 chunks lower than render distance setting.
  • MC-219507 – Beacon's power reverts back to previous one on world reload.

From 1.18

  • MC-242729 – Observer activating without any updates nearby, caused by /clone.
  • MC-243216 – Chunk render distance on servers seems shorter than in 1.17.1.
  • MC-243253 – Minecraft Realms screen is loading for long time.
  • MC-243796 – Random non fatal exceptions in console: Failed to store chunk ConcurrentModificationException.

Other

  • Fixed an issue that would cause players on low-bandwidth connections to get timeout errors when connecting to a server. [3]
  • Fixed a critical security issue in which attackers are able to execute code on others' devices (RCE exploit) via in-game messaging or other methods where the game logs a certain exploitable string, due to an upstream vulnerability in log4j2. [4][2][5]
