CVE-2024-31682Public exploit

Fingerprint authentication bypass via spoofed callback

Published Jun 3, 2024 · Updated Feb 13, 2025

Authentication bypass in Phone Cleaner: Boost & Clean 2.2.0 allows local users to unlock the Android app without a valid fingerprint. Its FingerprintManager authenticate call lacks a securely bound cryptographic parameter, so a Frida hook can spoof a successful callback. Exploitation requires control of an Android device running frida-server and grants access only to content protected by the app's fingerprint lock.
