Post Duplicator <= 2.36 - Authenticated (Contributor+) Protected Post Disclosure

The Post Duplicator plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.36 via the mtphr_duplicate_post() function due to insufficient restrictions on which posts can be duplicated. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract data from password protected, private, or draft posts that they should not have access to by duplicating the post.
