## Affected

- tagDiv tagDiv Composer: through 5.0

## Description

The tagDiv Composer plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘envato_code[]’ parameter in all versions up to, and including, 5.0 due to insufficient input sanitization and output escaping within the on_ajax_check_envato_code function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
