CraftOS-PC 2 is a rewrite of the desktop port of CraftOS from the popular Minecraft mod ComputerCraft using C++ and a modified version of PUC Lua, as well as SDL for drawing. Prior to version 2.8.3, users of CraftOS-PC 2 on Windows can escape the computer folder and access files anywhere without permission or notice by obfuscating `..`s to bypass the internal check preventing parent directory traversal. Version 2.8.3 contains a patch for this issue.

Common Weakness Enumeration

CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
