CVE-2022-21718 (opens in a new tab)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('');
});
});
