TPG Redirect <= 1.0.7 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The TPG Redirect plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.7. This is due to missing or incorrect nonce validation on the tpg_rd_show_settings() function. This makes it possible for unauthenticated attackers to invoke this function and modify the plugin's settings and arbitrary options via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
