How to Fix CVE-2022-21718
To remediate this vulnerability, upgrade all affected Electron dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install electron@13.6.6npm install electron@14.2.4npm install electron@15.3.5npm install electron@16.0.6npm install electron@17.0.0-alpha.6Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls electronHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2022-21718, inspect your project dependencies using npm:
npm ls electronAnalyze the terminal output to locate any version of Electron in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.6.6), your application is affected.
Note: The npm ls electron command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.

The device that is accessed is random and the attacker would have no way of selecting a specific device.\n\nAll current stable versions of Electron are affected.\n\n### Patches\nThis has been patched and the following Electron versions contain the fix:\n* `17.0.0-alpha.6`\n* `16.0.6`\n* `15.3.5`\n* `14.2.4`\n* `13.6.6`\n\n### Workarounds\nAdding this code to your app can workaround the issue.\n\n```js\napp.on('web-contents-created', (event, webContents) => {\n webContents.on('select-bluetooth-device', (event, devices, callback) => {\n // Prevent default behavior\n event.preventDefault();\n // Cancel the request\n callback('');\n });\n});\n```\n\nFor more information\nIf you have any questions or comments about this advisory, email us at security@electronjs.org.",
