    CVE-2026-50544 (GCVE-0-2026-50544)

    Vulnerability from nvd – Published: 2026-08-12 23:18 – Updated: 2026-08-14 22:23

    Title
    NortheBridge/luminalshine has Incorrect Permission Assignment for Critical Resource and Creation of Temporary File in Directory with Insecure Permissions
    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`.
