The "security setting" to which it is referring is the fact that JavaScript executing in a web browser does not have access to your clipboard. Which is a very good thing, because if it did, thousands of people would be having credit card numbers, passwords, addresses, etc. stolen from their clipboard on a daily basis.

That custom "paste" button you see in the visual editor is part of the webpage, and it requires JavaScript to function, so it can't access your clipboard. Why am I able to copy&paste with right click with no issues?
