Hello All, Dieter Maurer uncovered a potential security issue yesterday that necessitated a hotfix release. This hotfix addresses an important security issue that affects Zope versions up to and including Zope 2.3.2. The issue is related to ZClasses in that any user can visit a ZClass declaration and change the ZClass permission mappings for methods and other objects defined within the ZClass, possibly allowing for unauthorized access within the Zope instance. We *highly* recommend that any Zope site running versions of Zope up to and including 2.3.2 have this hotfix product installed to mitigate this issue. - http://www.zope.org/Products/Zope/Hotfix_2001-05-01/README.txt - http://www.zope.org/Products/Zope/Hotfix_2001-05-01/Hotfix_2001-05-01.tgz
