The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 1.9.8 via the 'pagelayer_builder_posts_shortcode' function due to insufficient restrictions on which posts can be included. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract data from private posts that they should not have access to.
