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.

js app.on('web-contents-created', (event, webContents) => { webContents.on('select-bluetooth-device', (event, devices, callback) => { // Prevent default behavior event.preventDefault(); // Cancel the request callback(''); }); });
