IP.B v3.4.1 is already a stable version of this software.
To reproduce this issue follow this steps(Obviously you have to be logged in):
1.Go to "My profile settings"
2.Find "Informations about profile" and button "Edit site 'About me'"
3. In that text area paste this code :"<body onload=alert(document.cookie)>"
(DOM based xss, and <script></script> works as well. There isn't any code sanitization, so you can enter here everything you want to).
Click : "Save".
4. Now go to your profile review(Again choose 'My profile') and here it is - persistent XSS disclosed.
