CVE-2025-66330

Protected-file access via app-lock verification bypass

Published Dec 8, 2025 · Updated Dec 8, 2025

Authentication bypass in Huawei HarmonyOS 5.0.1, 5.1.0, and 6.0.0 allows physically proximate attackers to access app-locked files. Huawei identifies the locus as app-lock verification in the file management app but has not disclosed the affected code path or validation error. Exploitation requires physical access and user interaction, and the documented consequence is limited to service confidentiality.
