Description

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('');
  });
});
