## Description

The Live Composer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Staff and Staff Social modules in all versions up to, and including, 2.1.23, due to insufficient output escaping of the heading titles, the view-all link, filter names, CSS class and carousel data attributes, the staff position and the staff social link URLs and link target. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
