minetest: Luanti (formerly Minetest) is an open source voxel game-creation platform
CVE-2026-41196 is fixed in 6 products on 1 platform, first by luanti 5.10.0+dfsg-5+deb13u1build0.26.04.1, released April 22, 2026. It is not reported as exploited. Patch Radar priority: High.
Luanti (formerly Minetest) is an open source voxel game-creation platform. Starting in version 5.0.0 and prior to version 5.15.2, 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).
