CVE-2022-21718

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. A vulnerability in versions prior to 17.0.0-alpha.6, 16.0.6, 15.3.5, 14.2.4, and 13.6.6 allows renderers to obtain access to a bluetooth device via the web bluetooth API if the app has not configured a custom select-bluetooth-device event handler. This has been patched and Electron versions 17.0.0-alpha.6, 16.0.6, 15.3.5, 14.2.4, and 13.6.6 contain the fix. Code from the GitHub Security Advisory can be added to the app to work around the issue.

Code from the GitHub Security Advisory can be added to the app to work around the issue.

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.6
• 16.0.6
• 15.3.5
• 14.2.4
• 13.6.6

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('');
  });
});
