4) Description of Vulnerability

Secunia Research has discovered a vulnerability in KubeBlog, which can
be exploited by malicious people to conduct script insertion attacks.

Input passed via the "website" parameter to post.php (when "id" is 
set) is not properly sanitised before being displayed to the user. 
This can be exploited to insert arbitrary HTML and script code, which 
will be executed in a user's browser session in context of an affected
