Zope Hotfix 2002-03-01 (Ownership Roles Enforcement)
by Matthew T. Kromer 01 Mar '02

This hotfix addresses an important security issue that may affect some users of Zope versions 2.2.0 through 2.5.x The issue involves the checking of security for objects with proxy roles. The context of the owner user that created the object with proxy roles was not being taken into account when determining access to the object with proxy roles. This flaw could allow users defined in subfolders of a site with sufficient privileges to access objects at higher levels in the site that they would not normally be able to access. We highly recommend that any Zope site running Zope 2.2.0 through Zope 2.5.x have this hotfix product installed to mitigate the issue. Zope 2.5.1 and 2.4.4 will contain a fix for the issue, at which time the hotfix can be removed.
