This page covers a release version that has a major issue under certain conditions.
 
The dedicated server for this version has a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.[1]

Trivia

  • On April 1, 2018, all textures in 1.12.2 were temporarily replaced – they were changed to include a smaller range of colors, falsely told to be the new textures previously announced (as a joke for April Fools).[3]
  • This is the last full release to use the panoramic background from Beta 1.8, as all of the subsequent updates had backgrounds related to the theme of the respective update.
  • This release holds the record of serving as the latest release of Minecraft: Java Edition for the longest time, at 303 days between its release on September 18, 2017 and the release of Java Edition 1.13 on July 18, 2018.
    • The previous record of serving as the latest release of Minecraft: Java Edition for the longest time was held by 1.11.2 (168 days).
  • This is the last version using numeric IDs, as The Flattening was implemented in Java Edition 1.13.
  • This version was released exactly seven years after Alpha v1.1.1 and Alpha v1.1.2.
