GHSA-3p22-ghq8-v749

Summary: Renderers can obtain access to random bluetooth device without permission in Electron

Details: ### Impact This vulnerability allows renderers to obtain access to a random bluetooth device via the [web bluetooth API](https://developer.mozilla.org/en-US/docs/Web/API/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(''); }); }); ``` For more information If you have any questions or comments about this advisory, email us at [email protected].
