CVE-2023-44117Network attack vector

Unauthenticated information disclosure via inaccurate trust relationships

Published Jan 16, 2024 · Updated Jun 17, 2025

Authentication bypass in Huawei HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 allows remote attackers to access service information. In distributed scenarios, the affected software accepts an inaccurate trust relationship; Huawei has not identified the component, request, or trust decision involved. No authentication or user interaction is required, and the reported consequence is limited to service confidentiality.
