Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection a malicious mod can trivially escape the sandboxed Lua environment to execute arbitrary code and gain full filesystem access on the user's device. This applies to the server-side mod, async and mapgen as well as the client-side (CSM) environments. This vulnerability is only exploitable when using LuaJIT. Version 5.15.2 contains a patch. On release versions, one can also patch this issue without recompiling by editing builtin/init.lua and adding the line getfenv = nil at the end. Note that this will break mods relying on this function (which is not inherently unsafe).
