CVE-2026-50544

Description

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`.
