Description
The JetStyleManager for Gutenberg WordPress plugin before 1.3.9 does not have CSRF protection on some of its AJAX actions, allowing attackers to make a logged-in user with the edit_posts capability (Contributor and above) delete or modify custom widget skins via a crafted request, provided they can trick the user into performing an action such as clicking a link.
