CVE-2025-68710 Overview
CVE-2025-68710 affects Easyelife App lock (also known as Fingerprint, Applock, or locker.app.safe.applocker) version 1.9.2 for Android. The app implements its PIN lock as a visual overlay instead of using Android's secure authentication APIs. A local attacker with physical access can bypass the lock screen by navigating cascading interface flows through exposed routes such as advertisement or browser intents. Successful exploitation grants access to protected apps like Chrome, leading to information disclosure and privilege escalation. The flaw maps to [CWE-288: Authentication Bypass Using an Alternate Path or Channel].
Critical Impact
A local attacker with physical device access can bypass the PIN lock entirely by exploiting intent-based navigation, accessing apps the user intended to protect.
Affected Products
- Easyelife App lock (locker.app.safe.applocker) version 1.9.2 for Android
- Distributed via the Google Play App Listing

Technical Details for CVE-2025-68710
Vulnerability Analysis
The vulnerability stems from an architectural decision to implement the app lock as a UI overlay rather than through Android's native authentication framework. Overlay-based locks rely on drawing a PIN prompt on top of the target activity, but the underlying activity remains active and reachable. When the overlay can be circumvented through alternate navigation paths, the authentication check is effectively skipped.
An attacker with physical access can trigger intents from advertisements, browser interactions, or other exposed routes that launch protected applications without first surfacing the lock overlay. Because the overlay is decoupled from the activity lifecycle, the protected app becomes accessible. Once Chrome or another locked application opens, the attacker can read stored data, sessions, and history, enabling information disclosure and downstream privilege escalation against the user account.
Root Cause
The root cause is improper use of Android's authentication primitives. Instead of gating sensitive activities through BiometricPrompt, KeyguardManager, or activity-level access controls, the application depends on a window overlay. This design fails to enforce authentication on alternate launch paths invoked via Intent actions, deep links, or system shortcuts.
Attack Vector
Exploitation requires physical access to an unlocked device with the vulnerable app installed. The attacker chains user-interface navigation by tapping advertisement links, browser intents, or notification handlers that pivot into a locked app. The overlay either fails to render in time or is dismissable through the cascading flow, leaving the protected activity exposed. No network access, credentials, or user interaction beyond physical handling is required. Refer to the GitHub CVE-2025-68710 Details for the documented bypass sequence.
Detection Methods for CVE-2025-68710
Indicators of Compromise
- Presence of locker.app.safe.applocker version 1.9.2 on managed Android devices.
- Unexpected launches of protected apps such as Chrome immediately following advertisement clicks or external intent handling.
- User reports of locked apps opening without PIN prompts after navigating from another application.
Detection Strategies
- Inventory Android devices using mobile device management (MDM) tooling to identify installations of locker.app.safe.applocker at version 1.9.2.
- Audit application launch telemetry for intent-driven transitions between browser or ad SDK contexts and apps marked as PIN-protected.
- Validate that mobile threat defense agents flag apps implementing authentication via SYSTEM_ALERT_WINDOW overlays rather than platform authentication APIs.
Monitoring Recommendations
- Monitor MDM compliance dashboards for installations of the affected package name and version.
- Track user-reported incidents involving bypassed app locks and correlate with the package inventory.
- Review enterprise browser and Chrome activity logs on managed devices for sessions occurring outside expected authentication windows.
How to Mitigate CVE-2025-68710
Immediate Actions Required
- Uninstall locker.app.safe.applocker version 1.9.2 from all managed Android devices until a fixed release is published.
- Replace third-party overlay-based lockers with Android's built-in screen lock, per-app pinning, or work profile separation.
- Enforce device-level encryption and a strong device passcode so that sensitive apps inherit platform authentication.
Patch Information
No vendor patch is referenced in the NVD entry for CVE-2025-68710 at the time of publication. Consult the GitHub Repository for AppLocker and the Google Play App Listing for any subsequent updates from the developer.
Workarounds
- Use Android's native BiometricPrompt and screen lock instead of relying on third-party overlay lockers.
- Configure managed Google Play to block installation of the affected package across the fleet.
- Sign users out of sensitive applications such as Chrome when devices are shared or left unattended, reducing data exposed if the lock is bypassed.
