Root Cause Analysis
The vulnerability stems from missing security declarations in Dexterity's WebDAV handling. WebDAVView is the primary handler for WebDAV operations in Dexterity, and security declarations (like @security.private
or explicit permission checks) would normally be required here. The FTI (Factory Type Information) components handle content creation/modification via WebDAV PUT requests. Without Zope security declarations (either via decorators or ZCML), these entry points would bypass Plone's permission system. While exact pre-patch code isn't available, Dexterity's WebDAV integration architecture and Plone's security patterns strongly suggest these components as vulnerable entry points.
