CVE-2024-13916

PIN disclosure via exposed content-provider query

Published May 30, 2025 · Updated Oct 3, 2025

Sensitive information exposure in Kruger&Matz AppLock 13 allows local users to read the application-lock PIN through a malicious app. The exposed com.android.providers.settings.fingerprint.PriFpShareProvider content provider lets its public query() method return the stored PIN to other apps. A malicious Android application needs no granted system permissions or user interaction, and disclosure compromises the PIN protecting selected applications.
