## Description

The Motors plugin for WordPress is vulnerable to unauthorized term creation due to a missing capability check and a non-fatal nonce check on the stm_listings_add_category_in AJAX action in all versions up to, and including, 1.4.129. The function also did not restrict which taxonomy the term was added to. This makes it possible for authenticated attackers, with Subscriber-level access and above, to insert new terms into arbitrary taxonomies on the site.
