Login Security, FireWall, Malware removal by CleanTalk <= 2.168 - Unauthenticated Stored Cross-Site Scripting via Page URL

The Login Security, FireWall, Malware removal by CleanTalk plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the page URL in all versions up to, and including, 2.168 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 a user accesses an injected page.
