=46rom a non-technical, PR-wise point of view let me add that
this type of "vulnerability" easily gets zope mentioned on lists
like bugtraq. The perception is that these thing really are=20
vulnerabilities.
Proof:

17.9. A posting named "Yet another path disclosure vulnerability"
targeted at oracle 9i appserver,
and
21.9. "RM Security Advisory: Xcache Path Disclosure Vulnerability"

both of which describe exactly the analogon to how zope handles
things.=20
