Description
The MP3 Audio Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the store popup content of playlists and tracks in all versions up to, and including, 5.14.2 due to insufficient input sanitization and output escaping. The content was returned by the load_post_by_ajax AJAX action after shortcode expansion without any HTML filtering. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts that execute whenever a user opens the store popup.
