Input validation vulnerability in Category and Taxonomy Meta Fields 1.0.0

There is a security issue with the Category and Taxonomy Meta Fields plugin for WordPress. This issue affects versions up to and including 1.0.0. The problem is that the plugin does not properly check for a security code before allowing certain actions to be performed. This means that someone who is not authorized can add or delete meta information about categories on a website, as long as they can trick the website administrator into clicking on a link.
