Unauthenticated data access and alteration via authentication bypass
Published Mar 5, 2026 · Updated Mar 5, 2026
Authentication bypass in the device authentication module of Huawei HarmonyOS 5.1.0 and 6.0.0 allows remote attackers to read or alter data. Huawei has not published which authentication check the module omits or mishandles, so the concrete input and code path remain undisclosed. Exploitation requires adjacent-network access and no prior privileges or user interaction; the public description does not identify the accessible or modifiable data.
