Bold Page Builder <= 5.3.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'data-text' Parameter

Vulnerability Description

The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the data-text parameter in all versions up to, and including, 5.3.5 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.
