 "title": "Duplicate Post <= 1.5.7 - Authenticated (Subscriber+) Missing Authorization to Original Post Slug Modification",
 "description": "The Duplicate Post plugin for WordPress is vulnerable to unauthorized modification of data in all versions from 1.5.1 up to, and including, 1.5.7. This is due to a missing edit_post capability check before the copy_post function renames the original post's slug when the 'take over original slug' option is enabled. This makes it possible for authenticated attackers, with subscriber-level access and above whose role has been granted access to the plugin, to change the slug of any post they can read and give the original URL to a copy.",
