EmbedPress – PDF Embedder, 3D PDF FlipBook, Google Reviews, YouTube Videos, Upload & Embed PDF documents 4.6.0 - 4.6.3 - Missing Authorization to Authenticated (Contributor+) Site-Wide Places Library Modification
The EmbedPress – PDF Embedder, 3D PDF FlipBook, Google Reviews, YouTube Videos, Upload & Embed PDF documents plugin for WordPress is vulnerable to unauthorized access in versions 4.6.0 through 4.6.3. This is due to missing authorization check on the /google-reviews/places REST API route, which used can_edit() (requiring only edit_posts, held by Contributors) instead of can_manage() (requiring manage_options) for operations that mutate a site-wide data store. This makes it possible for authenticated attackers, with contributor-level access and above, to modify the site-wide Google Reviews saved-places library, deleting administrator-configured entries and injecting their own, which are rendered publicly across the site.
