LearnPress <= 4.1.3.1 - Stored Cross-Site Scripting via $custom_profile

The LearnPress WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient escaping on the $custom_profile parameter found in the ~/inc/admin/views/backend-user-profile.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 4.1.3.1.
