Hi. As a reminder: If nobody is able to help with this, I'll disable the insecure view registration in Zope2 and release new versions Tuesday 13th.
>From my understanding of the code, Zope 2 itself is not vulnerable, as there's no registrations for IFactory utilities included. But in any system that has such registrations, anonymous users should be able to create any such content item in any location.
