The Buzz Club – Night Club, DJ and Music Festival Event WordPress Theme theme for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on the 'cmsmasters_hide_admin_notice' function in all versions up to, and including, 2.0.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update option values to 'hide' on the WordPress site. This can be leveraged to update an option that would create an error on the site and deny service to legitimate users or be used to set some values to true such as registration.

The CMSMasters Elementor Addon plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple widgets in all versions up to, and including, 1.14.7 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

The CMSMasters Content Composer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's multiple shortcodes in all versions up to, and including, 1.8.8 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
