Input validation vulnerability in PJ | Life & Business Coaching Site Template 3.0.0

A certain theme for WordPress called PJ | Life & Business Coaching has a security issue called Local File Inclusion. This means that unauthorized people can access and run any files they want on the server, including files with harmful PHP code. This can lead to bypassing security measures, gaining access to private information, and executing malicious code, even if the file is supposed to be safe, like an image.
