CVE-2024-13917

System-privileged intent execution via exported activity

Published May 30, 2025 · Updated Jun 10, 2025

Intent injection in Kruger&Matz AppLock 13 allows local users to invoke protected apps with system privileges through a malicious app. The exported com.pri.applock.LockUI activity accepts an arbitrary intent from an app with no Android permissions and launches it with AppLock's system-level privileges. Exploitation requires the protecting PIN or active user entry of that PIN; successful use grants the injected intent the privileges available to the targeted protected app.
