Improper authentication in HUAWEI Mate 20 Pro before 10.0.0.175(C00E69R3P8) allows physically proximate attackers to bypass Digital Balance. The application-name validation path accepts a crafted APK name and presents the application as a normal one. Exploitation requires physical possession of the phone; the reported consequence is limited to bypassing the Digital Balance control.
