## Description

The WP Ghost (Hide My WP Ghost) – Security & Firewall plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'replaceHeadersAndTags' function in versions up to, and including, 7.0.12 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 clicks on the injected link.
