Plone developer reports:
This is an escalation of privileges attack that can be used by
anonymous users to gain access to a Plone site’s administration
controls, view unpublished content, create new content and modify a
site’s skin. The sandbox protecting access to the underlying
system is still in place, and it does not grant access to other
applications running on the same Zope instance.
