CVE-2026-50544

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`.

Summary		(es) NortheBridge/luminalshine es un host de transmisión de juegos compatible con Sunshine para Moonlight. Antes de la versión 26.05.0-rc4, existe una brecha latente en una instalación predeterminada: el archivo en ’src/platform/windows/misc.cpp’ reside en ’C:\ProgramData\LuminalShine\config\apps.json’ y es creado por el servicio ’SYSTEM’. Bajo la herencia predeterminada de Windows para ’C:\ProgramData’, eso otorga a ’BUILTIN\Users’ solo permisos de Lectura+Ejecución - no de escritura - por lo que la EoP canónica no se activa realmente en una instalación limpia. La versión 26.05.0-rc4 contiene un parche para el problema. Como solución alternativa, utilice DACL de condición predeterminada para ’ProgramData’.
