An AJAX action registered by the WPBakery Page Builder (Visual Composer) Clipboard WordPress plugin before 4.5.6 did not have capability checks nor sanitization, allowing low privilege users (subscriber+) to call it and set XSS payloads, which will be triggered in all backend pages.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
