{"id":"DEBIAN-CVE-2026-41196","details":"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).","modified":"2026-09-14T17:03:33.071416214Z","published":"2026-04-23T02:16:17.900Z","upstream":["CVE-2026-41196"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-41196"}],"affected":[{"package":{"name":"luanti","ecosystem":"Debian:13","purl":"pkg:deb/debian/luanti?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.0+dfsg-5+deb13u1"}]}],"versions":["5.10.0+dfsg-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41196.json"}},{"package":{"name":"luanti","ecosystem":"Debian:14","purl":"pkg:deb/debian/luanti?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.2+dfsg-1"}]}],"versions":["5.10.0+dfsg-5","5.14.0+dfsg-1","5.14.0+dfsg-2","5.14.0+dfsg-3","5.15.1+dfsg-1","5.15.1+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41196.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
