The WPBakery plugin before 6.4.1 for WordPress allows XSS because it calls kses_remove_filters to disable the standard WordPress XSS protection mechanism for the Author and Contributor roles.
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.
