 "title": "Duplicate Post <= 1.5.7 - Authenticated (Subscriber+) Missing Authorization to Post Publishing via Post Duplication",
 "description": "The Duplicate Post plugin for WordPress is vulnerable to unauthorized post publishing in all versions up to, and including, 1.5.7. This is due to the copy_post function of the cdp_action_handling AJAX action giving copies the original post's status and author, based on settings sent in the request, without checking the current user's publish_posts and edit_others_posts capabilities. This makes it possible for authenticated attackers, with subscriber-level access and above whose role has been granted access to the plugin, to create published copies of posts they can read, with a title prefix and suffix they choose, and attribute those copies to other users.",
