npm/cordova-plugin-fingerprint-aio

Reachable Assertion

cordova-plugin-fingerprint-aio is a plugin provides a single and simple interface for accessing fingerprint APIs on both Android 6+ and iOS. The exported activity de.niklasmerz.cordova.biometric.BiometricActivity can cause the app to crash. This vulnerability occurred because the activity didn't handle the case where it is requested with invalid or empty data which results in a crash. Any third party app can constantly call this activity with no permission. A 3rd party app/attacker using event listener can continually stop the app from working and make the victim unable to open it. of the cordova-plugin-fingerprint-aio does not export the activity anymore and is no longer vulnerable. If you want to fix older versions change the attribute android:exported in plugin.xml to false. Please upgrade to as soon as possible.

All versions before 5.0.1

Upgrade to version 5.0.1 or above.
