WP Visitor Statistics (Real Time Traffic) < 8.3 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The WP Visitor Statistics (Real Time Traffic) plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 8.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
