Input validation vulnerability in Radio Buttons for Taxonomies 2.0.6

The Radio Buttons for Taxonomies plugin for WordPress is not secure in versions up to and including 2.0.5. This means that a malicious user can take advantage of a security issue in the plugin to get a site administrator to perform an action, like clicking a link, without the administrator’s knowledge. This is done by bypassing a security feature called nonce validation on the save_single_term() function.
