Symlink Check
Symlink Check shows a warning screen when a world is opened through a symbolic link that is not on the allowed list.
What it does
A symbolic link can point a world folder at a location the player did not intend, and the help article cited by the author notes that such an attack can cause permanent data loss. The mod checks for this when a world is opened and displays a warning screen if a symbolic link is found, unless its target is listed in symlinks.txt. The author notes that the detection and warning screen were not ported to lower versions, which is why the mod is limited to 1.19.4. Either side can run it, and neither needs it. Released under the Apache License 2.0 and open source, with public links to the source code and issue tracker.

What the author says
