Where did you get the value "7258002722" for the _wpnonce parameter from?

Copy/paste from a session when you where logged in as admin? That doesn't count then.

And: Next time please do not report security vulnerabilities here, but by following the instructions at http://codex.wordpress.org/FAQ_Security
