This is very iffy. For example, the web site could just be sending a
message to your browser to display the clipboard. This does NOT mean that
the remote site knows anything about your clipboard, just that it has told
your own browser on your own machine to display the clipboard, a totally
secure thing to do.

Are you sure this is anything different than that, ie, that the remote site
can get the contents of your clipboard?
