Windows 10 Mobile Security Feature Bypass Vulnerability

A security feature bypass vulnerability exists in Windows 10 Mobile when Cortana allows a user to access files and folders through the locked screen. An attacker who successfully exploited this vulnerability could access the photo library of an affected phone and modify or delete photos without authenticating to the system.

To exploit the vulnerability, an attacker would require physical access and the phone would need to have Cortana assistance allowed from the lock screen.
