Prior to the verified source fix, the doc category index refresh resolves linked titles for private messages or restricted category topics without enforcing the viewer\u0027s authorization. A user who can edit the index topic can use this behavior to learn titles that the user is not authorized to view, although the advisory does not establish access to topic contents.
