Which packages are affected by GHSA-7vfx-hfvm-rhr8?

GHSA-7vfx-hfvm-rhr8 affects the following packages: cordova-plugin-fingerprint-aio (npm). Ecosystems affected: npm.

How do I fix GHSA-7vfx-hfvm-rhr8?

Update cordova-plugin-fingerprint-aio to 5.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7vfx-hfvm-rhr8 is resolved across your whole dependency graph.

How do I detect GHSA-7vfx-hfvm-rhr8 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cordova-plugin-fingerprint-aio. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-7vfx-hfvm-rhr8 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-7vfx-hfvm-rhr8?

O3 pinpoints whether GHSA-7vfx-hfvm-rhr8 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-7vfx-hfvm-rhr8 actively exploited in the wild?

No public exploit code has been indexed for GHSA-7vfx-hfvm-rhr8 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-7vfx-hfvm-rhr8?

GHSA-7vfx-hfvm-rhr8 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 25th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-7vfx-hfvm-rhr8?

GHSA-7vfx-hfvm-rhr8 is classified as Reachable Assertion (CWE-617). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-7vfx-hfvm-rhr8 published, and has it been updated?

GHSA-7vfx-hfvm-rhr8 was published on November 2, 2023 and was last updated on March 13, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.

Description

Summary:

Sending a specially crafted intent with an invalid/empty extras de.niklasmerz.cordova.biometric.BiometricActivity can cause the app to crash. sending the intent repeatedly can prevent the app using this plugin from working, resulting in a denial of service (DoS) condition.

Impact

A 3rd party app/remote attacker can exploit this vulnerability by sending a malicious intent to the target device, causing the app using this plugin from working to crash or become unresponsive, resulting in a denial of service (DoS) condition.

Mitigation

Version 5.0.1 of the cordova-plugin-fingerprint-aio doesn't export the activity anymore and is no longer vulnerable.

If you want to fix older versions change the attribute android:exported of this code snippet in plugin.xml to false:

<config-file target="AndroidManifest.xml" parent="application">
      <activity android:name="de.niklasmerz.cordova.biometric.BiometricActivity" android:theme="@style/TransparentTheme" android:exported="false"/>
</config-file>

Patches

Please upgrade to version 5.0.1 as soon as possible.

Please check out the release on GitHub.
