The Education Addon for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.3.1 via the naedu_elementor_template shortcode due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract information from posts that are not public, including drafts, password protected, and restricted posts. This applies to posts created with Elementor only.
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
