Descripción
The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘percentage’ parameter in all versions up to, and including, 5.4.5 due insufficient input sanitization output escaping. This makes it possible authenticated attackers, with Contributor-level access above, inject arbitrary web scripts pages that will execute whenever a user accesses an injected page.
