Summary
The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Biographical Info' meta field parameter in all versions up to, and including, 3.15.7 due to insufficient input sanitization and output escaping.
