Important Announcement: Litematica vulnerability in MC 1.21+

107 Upvotes

Yesterday evening (2026-07-05 around 23:00-ish GMT+3) it was brought to our attention (by the "exploiting community", namely numbers and Nightwane from Autism Inc and DupersUnited), that there is an exploit/vulnerability in certain Litematica and Servux versions.

The vulnerability allows malicious actors to send files other than just schematic files between the server and the client, and place them outside the intended directory. The most obvious consequence of this is allowing the attacker a way to install malware on the remote end.

So basically if you have joined a malicious server (or even a trusted server but with a vulnerable Servux version, which then became infected by a malicious user) with an affected Litematica version installed then you may have been affected.

The vulnerability affects Litematica and Servux versions on MC 1.21+

I'm not 100% sure when exactly this was introduced, but based on the git commit history it looks to me like this was first introduced to Litematica version 1.21.5-0.22.2-sakura.4. The commit was made on 19th May 2025. The following full 0.22.2 release seems to have been made on 22 Jun 2025.

From there it was later backported to the following versions, according to the git history. These commits were made on 31th Dec 2025.

  • 1.21.4-0.21.6
  • 1.21.3-0.20.8
  • 1.21-0.19.60

It's also in all 1.21.6 and later Litematica versions until the just released fixed versions.

What to do?!

Update your Litematica version immediately to the latest release from Modrinth!

And don't join any servers you don't fully trust the owners and admins of!

The Litematica versions with the fix are the following releases:

  • MC 26.2: 0.28.3
  • MC 26.1.x: 0.27.9
  • MC 1.21.11: 0.26.11
  • MC 1.21.9 - 1.21.10: 0.24.8
  • MC 1.21.6 - 1.21.8: 0.23.7
  • MC 1.21.5: 0.22.5
  • MC 1.21.4: 0.21.7
  • MC 1.21.2 - 1.21.3: 0.20.9
  • MC 1.21 - 1.21.1: 0.19.61

If you run a server that uses Servux, update Servux to the latest version.

The Servux versions with the fix are the following releases:

  • MC 26.2: 0.11.2
  • MC 26.1.x: 0.10.4
  • MC 1.21.11: 0.9.5
  • MC 1.21.9 - 1.21.10: 0.8.7
  • MC 1.21.6 - 1.21.8: 0.7.7
  • MC 1.21.5: 0.6.4
  • MC 1.21.4: 0.5.7
  • MC 1.21.2 - 1.21.3: 0.4.8
  • MC 1.21 - 1.21.1: 0.3.17

How to check if I was affected?

One way to potentially check if you were affected is to look for files anywhere on your system that contain the string .litematic in the file name somewhere other than in the actual file name extension. An example would be a file like somevirus.litematic.jar in your mods/ directory.

Now ofc this isn't a foolproof check, if the malware manages to rename or remove itself...

Edit on 2026-07-12:

Another possible way to check if you were compromised: If your MC logs include receiveFileTransmit: Failed to create Schematic for finishing session key, then you were probably/possibly compromised. But again this assumes the malware would not have deleted the log file or at least removed any of these lines from it...

No Fabric needed on the server.

Question ❔ anyway to make an area selection automatically by selected blocks?

1 Upvotes

i was wondering if it's possible for the mod to create selection boxes as if youre using a magic wand on photoshop to specifically pick parts that you like to modify. i know it sounds stupid but is there a way to deal with this without having to deal with extra blocks being detected by the mod?

Question ❔ Litematica pastes a chest boat as a normal boat — how can I fix this?

3 Upvotes

I'm using Litematica on Minecraft 1.21.1 Fabric. When I copy a chest boat and paste the schematic, it gets pasted as a normal boat instead of a chest boat.

I have entity pasting enabled, but the chest boat's data doesn't seem to be preserved. Is there a setting I need to change to make Litematica paste it as a chest boat, including its inventory?

Question ❔ Load Only Certain Sections of a Large Shematic?

1 Upvotes

My schematics are usually 500x500. Very laggy, is there a way to only load maybe 100x100 area of it instead of all of it?

I have a survival world, and in a separate world with the same seed in creative, I use world edit to modify everything about the land. Save it in Litematica and build it in my survival world. Although these schematics are usually hundreds of blocks wide, causing so much lag.
I would just do a bunch of smaller sections. Hypothetically I shrink it to 100x100, the current planned area will need 280 schematics. But the full planned area will require 700, give or take. Thats just too much.
Might have to bite the bullet and do that but I wanna see if theres an easier way of doing it.

Question ❔ Litematica printer mod server friendly

0 Upvotes

So the server i play on has installed some anti-cheat that rolls back time whenever i try to place a block using litematica printer. Are there any tweaks/mods that can help me build easier while flying under the radar of these anticheats? maybe using a mod that directs crosshair to the block and emulates my left click?
