{"id":"CVE-2026-50544","summary":"NortheBridge/luminalshine has Incorrect Permission Assignment for Critical Resource and Creation of Temporary File in Directory with Insecure Permissions","details":"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`.","aliases":["GHSA-52q6-5x97-2747"],"modified":"2026-08-16T03:31:07.430032170Z","published":"2026-08-12T23:18:03.735Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50544.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-379","CWE-732"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50544.json"},{"type":"ADVISORY","url":"https://github.com/NortheBridge/luminalshine/security/advisories/GHSA-52q6-5x97-2747"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50544"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/northebridge/luminalshine","events":[{"introduced":"0"},{"fixed":"c3e98d6cd0b3ae61e878bf3e74ace590b94e3b04"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"26.05.0-rc4"}]}}],"versions":["26.05.0-rc3.hfx4","26.05.0-rc2","26.05.0-rc1","26.05.0-beta.7","26.05.0-beta.6","26.05.0-beta.5","26.05.0-beta.4","26.05.0-beta.3","26.05.0-beta.2","26.05.0-beta.1","26.04.0-alpha.7","26.04.0-alpha.6","26.04.0-alpha.5","26.04.0-alpha.4","26.04.0-alpha.3","26.04.0-alpha.2","26.04.0-alpha.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50544.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H"}]}
