Till this version it was possible to inject authenticated users external URLs as start URLs for their GUI.
An attacker could use this to make an authenticated GUI user open a page of his choice when the user clicks on a prepared link.
One example URL which could be used: index.py?start_url=//heise.de
Thanks to Marcel Bilal for reporting the issue!
