Vvveb 1.0.8.4 through 1.0.8.6 contains an authorization bypass vulnerability in the content/revisions revision action that lets low-privileged Authors read other authors' revisions. Attackers can supply a post_id, language_id, and created_at timestamp to retrieve private unpublished drafts, because the revision() action lacks the admin_id ownership restriction.
