Wordpress has a wide range of themes to choose from with new ones being added every day. With so many themes, and most of them created by unknown developers, it is hard to check the authenticity of a theme for hidden or encoded links.

Theme Authenticity Checker is a Wordpress plugin which checks the authenticity of a wordpress theme. It check the theme for any hidden or obfuscated external links stealing away your traffic or using your web-server as a bot server. But Theme Authenticity Checker does not correct any detected problem.
Now the good question is what to do with a vulnerability?
Well, to start with you can contact the theme author for details of the link. Otherwise, Theme Authenticity Checker also directs you to the Wordpress Theme Editor, with the file opened in the editor.
