Cross domain policies are enforced by the browser. If you’re using a third party app, guess what you’re using as a browser.
Want an easy example of this? Userscrips on Firefox. Install GreaseMonkey, and you can run whatever the hell you want on any webpage. Keylogging, mouse movements, clicks and navigations.

I was responding to your claim of “not happening, impossible” with proof of it being possible, and actually fairly easy to implement.
