Severity: Malicious users can steal session cookies, 
allowing administrative access to the admin panel

Problem:
Ok the problem is in the way the [img] tags check for 
the "http://";. The [img] tags checks for the "http://"; 
when you posting a new topic but it doesnt check for 
it while your editing one. So it will allow you to insert 
malacious code while you editing a post.

Proof of concept:

Make a new post, then "EDIT" the post and in the 
body of the post insert this code

[IMG]javascript:alert(document.cookie)[/IMG]

an alert box should pop up displaying your cookies!

Fix: 

make [IMG] tags check for "http://"; when editing a 
post.
