CVE-2023-52373Network attack vector

Unauthorized file sharing via failed permission verification

Published Feb 18, 2024 · Updated Mar 27, 2025

Improper permission verification in Huawei HarmonyOS and EMUI allows remote attackers to share files without authorization. The content sharing pop-up module fails to enforce the intended permission check before sharing a selected file, but Huawei has not disclosed the responsible function or request path. Exploitation requires network reachability but no account or user interaction; impact is limited to files exposed through unauthorized sharing.
