CVE-2022-21718 is a low-severity (CVSS 3.4) CWE-668 vulnerability in electron. A fix is available for electron — see the affected versions and patch details below.
Renderers can obtain access to random bluetooth device without permission in Electron
EPSS Exploitation Probability
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
CVE-2022-21718 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 378,156 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.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
electronnpmDescription
Impact
This vulnerability allows renderers to obtain access to a random bluetooth device via the web bluetooth API if the app has not configured a custom select-bluetooth-device event handler. The device that is accessed is random and the attacker would have no way of selecting a specific device.
All current stable versions of Electron are affected.
Patches
This has been patched and the following Electron versions contain the fix:
17.0.0-alpha.616.0.615.3.514.2.413.6.6
Workarounds
Adding this code to your app can workaround the issue.
app.on('web-contents-created', (event, webContents) => {
webContents.on('select-bluetooth-device', (event, devices, callback) => {
// Prevent default behavior
event.preventDefault();
// Cancel the request
callback('');
});
});

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for electron, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update electron to 13.6.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-21718 is resolved across your whole dependency graph.
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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2022-21718 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2022-21718. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-21718 in your dependencies?
O3 Security finds CVE-2022-21718 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
