Input validation vulnerability in Redux Framework 4.1.20

The Gutenberg Template and Pattern Library & Redux Framework plugin for WordPress is vulnerable to a security flaw. This vulnerability was found in versions up to and including 4.1.20. It is possible for someone who is not authorized to make changes to settings by tricking a site administrator into performing an action such as clicking on a link. This is because the save() function does not have the correct security measures in place.
