CVE-2022-1959Public exploit

Authentication bypass via forged fingerprint callback

Published Sep 30, 2022 · Updated May 20, 2025

Authentication bypass in SpSoft AppLock - Fingerprint 7.9.29 allows physically proximate attackers to unlock protected apps. The fingerprint flow trusts a forged onAuthenticationSucceeded callback carrying a null CryptoObject without binding access to cryptographic proof of a valid scan. Exploitation requires physical device access, a configured fingerprint lock, and process instrumentation through Frida.
