EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

GHSA-7vfx-hfvm-rhr8 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 377,636 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cordova-plugin-fingerprint-aio, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    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.

  3. Workarounds

    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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-7vfx-hfvm-rhr8 can be triaged on real exposure rather than presence alone.

Tailored to GHSA-7vfx-hfvm-rhr8. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
