Hi.
Now I'm using Stattraq instead of doc referers. And when I clicked a referer from an wpmu site (http://xxx.xxx.com/wp-admin/plugins.php), I jumped to his(or her) plugins.php on admin page. I was using Opera 8 then, and had opened several wp-admins on my test server with another tabs.
I guess Opera is a little odd when it handles cookies, because I experienced a lot of session troubles when I logged in WPMU with Opera.
When I jumped that someone's plugin page my user level was proboubly 0. But it is not confrotable at all that someone can possibly see which plugin you have installed, isn't it? I think this is a security hole.
Is there possibility to fix this issue?
