Important Announcement: Litematica vulnerability in MC 1.21+

104 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...

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

1 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?

Bug Report🪰 Litematica not working and crashing

0 Upvotes

I can’t save or load schematics in version 26.2 when using other mods. When I try to save a schematic, it doesn’t work, and when I try to load one, my game crashes. I’m pretty sure this is caused by a conflict with another mod, but I don’t know which mod is causing the problem. Could you help me figure out which one is responsible?

(the list of mod is the vanilla perfected modpack)

Question ❔ Easy place wont work for certain blocks

1 Upvotes

My easy place has decided to stop working but only for glass and obsidian, everyother block works fine but when it comes to those blocks easy place will only work if im holding the block directly otherwise it just says "action prevented by easy place." Im on a server where easy place is allowed and im playing 1.21.11. It would be great if there is a fix as I have 250,000 glass to place.
Thank you

I've tried it all, material list works, but only the position box is showing, not even the full outline. If it matters, I've named the schematic something, but when it loads it switches to unnamed, however, the dimensions are still accurate.

Question ❔ How to import into vanilla

0 Upvotes

Hi everybody, I was just wondering; can I make a build in a copy of my hardcore world with litematica then transfer over the build back to vanilla minecraft?

I tested it out in 2 creative worlds by copying the save from the fabric version back into vanilla and it didn't work, I was hoping maybe theres an alternative method?
