How to fix?

Upgrade electron to version 13.6.6, 14.2.4, 15.3.5, 16.0.6, 17.0.0-alpha.6 or higher.

Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Improper Access Control 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.

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('');
  });
});
