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.
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
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('');
});
});
