Description
The Xpro Addons plugin for WordPress is vulnerable to unauthorized creation of data due to a missing capability check on the `get_menu_content_editor()` function in all versions up to, and including, 1.5.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create arbitrary published posts of the `xpro_content` custom post type with attacker-controlled titles. The created posts are publicly queryable on the front-end, enabling content injection, SEO spam, and database pollution.
