Create Bugfix: Clipboard Patch

by cff1028

Create Bugfix: Clipboard Patch repairs the clipboard item from the Create mod, closing an item duplication exploit that malicious clipboards could trigger.

NeoForgeServer required, client optionalMIT LicenseOpen source1.21.1

What it does

Clipboards carrying illegal data components could be used to duplicate items. The patch intercepts the player's item-drop event, detects a dropped create:clipboard, and automatically replaces it with a clean clipboard instance. Only whitelisted components, such as the page content and clipboard type, are migrated into the new item, and illegal components are discarded. Normal clipboard function, including its text and icons, is kept.

The mod needs Create to run, and it works with Create versions larger than 6.0. Only the server has to run the patch; players may leave it out, and it adds nothing they must install. Files target NeoForge for 1.21.1 only, with 1.0.0 as the latest file, released on 2025-07-22 under the MIT License. The code is open source, and the source repository and issue tracker are linked publicly.

Key features

  1. Clipboard drop interception

    The patch hooks the player item-drop event and checks each dropped item for the create:clipboard identifier.

  2. Component whitelisting

    Only approved data components survive the replacement, which removes components that could carry the duplication exploit.

  3. Clean clipboard replacement

    A fresh clipboard is generated in place of the dropped one, keeping page content and clipboard type intact.

  4. Permanent exploit fix

    Item duplication through containers and other illegal components is blocked, so the fix applies without manual cleanup.
