Java Edition 1.9.3
This page covers a release version that has a critical issue under certain conditions.
The dedicated server for this version includes 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]

Other editions with a version "1.9.3":
1.9.3 is a minor update to Java Edition released on May 10, 2016,[2] which adds the /stopsound command, limits the Y-value of /tp, and improves Minecraft 's networking libraries. It is not compatible with 1.9.2 servers. However, due to an incorrect snapshot warning when loading a world saved in an older version, 1.9.3 was replaced by 1.9.4 on the same day.
Additions
Commands
- Permits the player to choose which specific sounds should be stopped from playing.
- Syntax:

- Syntax:
Changes
Commands
/tp
- No longer teleports the player to a y-coordinate outside the range −512 to 512.
General
Networking
- As of the release of this version, the Netty networking library that Minecraft uses, now checks sessionserver.mojang.com/blockedservers when connecting to a multiplayer server, and if the server is on the blocked server list, it reports to the user that the server is unavailable.
- The blocklist consists of servers in violation of the Minecraft EULA (End User License Agreement).
- This affects all versions that depend on the Netty library, back to version 1.7.2 snapshot 13w41a.
- Better memory use of pathfinding and biome caching.
- This prevents memory leaking.
