https://notcve.org/view.php?id=CVE-2021-43849

In versions prior to 5.0.1 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. • https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/commit/27434a240f97f69fd930088654590c8ba43569df https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/releases/tag/v5.0.1 https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/security/advisories/GHSA-7vfx-hfvm-rhr8 • CWE-617: Reachable Assertion •
