It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-50544 in the wild and no public exploit code.\n\nAffected product: NortheBridge luminalshine. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-50544/ (Markdown: https://insights.sbomify.com/CVE-2026-50544/index.md)","id":"CVE-2026-50544","markdown":"https://insights.sbomify.com/CVE-2026-50544/index.md","name":"CVE-2026-50544","record":{"aliases":["GHSA-52q6-5x97-2747"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Game streaming host","requires_auth":"high_privilege","summary":"Local attackers can escalate privileges if insecure permissions are applied to the configuration file, allowing modification of critical resources.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-379","name":"Creation of Temporary File in Directory with Insecure Permissions"}],"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.
