Limiting In-app Navigation, Use of `openExternal`, and Electron.js Version Upgrade

[masood]

Summary: Thank you for designing the Infiniti Clips Desktop Application making it open-source and available. The application does a great job of following secure practices. We list pointers of concern below that can help make the application more secure.

1. [In-app Navigation] The application currently limits in-app navigation with a listener on the ‘new-window’ event [Ref]. Electron has updated this event and recommends using setWindowOpenHandler. [Link] Similarly, it may be useful to also set an event.preventDefault() on the ‘will-navigate’ event as a precaution.
2. [Use of openExternal] We observed that the application uses shell.openExternal(). It may be helpful to consider sanitizing the URL before making this call. Passing a file-based link, for example, can lead to triggering an executable.
3. [Keeping up-to-date w/ Electron.js]: The application uses an old version of Electron.js (v21.2.0) and Chromium which are vulnerable to numerous known V8 and Blink attacks. Upgrading to an even newer version will be a great idea as well [Link]

Thank you!
