Description
The Ace Post Type Builder plugin for WordPress is vulnerable to unauthorized custom taxonomy deletion due to missing authorization validation on the cptb_delete_custom_taxonomy() function in all versions up to, and including, 1.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary custom taxonomies.
