The WP Ghost (Hide My WP Ghost) – Security & Firewall plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 5.4.01 via the showFile function. This makes it possible for unauthenticated attackers to read the contents of specific file types on the server, which can contain sensitive information.
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory.
