Enfold < 6.0.4 - Contributor+ Stored XSS via wrapper_class and class Parameters

Description

The theme is vulnerable to Stored Cross-Site Scripting via the ‘wrapper_class’ and 'class' parameters due to insufficient input sanitization and output escaping. 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.
