CVE-2026-50544
CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H
Summary
NortheBridge/luminalshine is a Sunshine-compatible game stream host for Moonlight. Prior to version 26.05.0-rc4, a latent gap exists on a default install, the file at src/platform/windows/misc.cpp lives at C:\ProgramData\LuminalShine\config\apps.json and is created by the SYSTEM service. Under Windows' default C:\ProgramData inheritance, that gives BUILTIN\Users only Read+Execute — not writable — so the canonical EoP doesn't actually trigger on a vanilla install. Version 26.05.0-rc4 contains a patch for the issue. As a workaround, use default condition DACLs for ProgramData.
