Minecraft through 1.19 and 1.20 pre-releases before 7 (Java) allow arbitrary file overwrite, and possibly code execution, via crafted world data that contains a symlink.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
