No, for two reasons:

Firstly, I assume your management page is a dtml file on disk, not a
dtml object stored in the ZODB. dtml files bypass *all* security
checks. 

Secondly, all objects that inherit from OFS.Item.SimpleItem (that is,
almost all high level objects) have the
__allow_access_to_unprotected_subobjects__ flag set. Your method would
be callable from through-the-web dtml too.


The basic rules of Zope security are fairly easy; its the exceptions
that cause the problems.
