3D FlipBook – PDF Embedder, PDF Flipbook Viewer, Flipbook Image Gallery <= 1.16.17 - Missing Authorization to Unauthenticated Private/Draft Flipbook Data Exposure

The 3D FlipBook – PDF Embedder, PDF Flipbook Viewer, Flipbook Image Gallery plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the send_post_pages_json() function in all versions up to, and including, 1.16.17. This makes it possible for unauthenticated attackers to retrieve flipbook page metadata for draft, private and password-protected flipbooks.
