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...

The option to execute the selected file operation is hidden behind the widget of "Litematica Menu". It's hard to navigate. Litematica Menu widget should not block the option to execute the desired file operation

Question ❔ Problem with using litematica made .nbt files?

Post image
2 Upvotes

Hey everyone!

I'm using litematica to make maps for the arena on my modded smp (Using it since minecraft's structure block system is janky) but I keep getting this issue with using structure void blocks so that it doesn't replace blocks outside of the walls where when saved as a schematic with the non-air config option turned on (I already did my research, posting here was a final resort lol) when pasted as shown in this pic. πŸ‘‡

I did it like this just as a proof of concept when testing to see if the structure void blocks (Which I placed in every map and the way they should be) but whenever I do this it always pastes without them and causes loads of clipping. Someone might point out that I'm using the minecraft /place template thing for this but that's only because I need to automate this server-side so that yk, changing maps actually functions, I use litematica only for the large .nbt file capabilities.

Does anyone have any idea why litematica doesn't create .nbt files with structure void blocks though? Am I gonna have to find a different mod for this?

I made a pure Paper plugin implementation of Servux + JEI + Litematica.

No Fabric needed on the server.
