Input validation vulnerability in 3DPrint Lite 2.0.9.9

The 3DPrint Lite plugin for WordPress has a security issue that affects all versions up to 2.0.9.9. This is because the plugin does not properly check for a special code, called a nonce, when performing certain actions. This means that someone who is not logged in can make changes to the plugin’s settings if they can convince the site administrator to do something, like click on a link.
