## Description

The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Google Maps element's static image map in all versions up to, and including, 5.9.11. This is due to insufficient input sanitization and output escaping: the latitude, longitude, marker icon, custom style and API key values were concatenated into an HTML <img> string and appended to the page. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that execute whenever a user accesses an injected page.
