Forum Restricted Forums Security Exploit Help

[محروم.كوم]

Okay, so here's the problem. On the forums that me and some other people manage, we have forum section for Staff Members only. These forums can only be viewed and posted in by users in a staff usergroup (Admin, Moderator, etc.). However, I just became awre of the fact that friends of staff member could also see what the staff members were posting in these restricted forums by going to their own profile and looking at their activity. Here's an example:

The user "Sate" would be able to see that the user "Dragons5439" posted in a restricted forum by going onto his own profile page. The forums we are using are currently running vBulletin 4.2 Patch Level 2. Does level 3 happen to resolve this issue?
