Visitor Traffic Real Time Statistics <= 8.4 - Unauthenticated Stored Cross-Site Scripting

The Visitor Traffic Real Time Statistics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'page_title' parameter in all versions up to, and including, 8.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an admin user accesses the Traffic by Title section.
