Summary

The iubenda WordPress plugin prior to version 3.3.3 contains a security issue where it lacks proper authorization checks and is vulnerable to Cross-Site Request Forgery (CSRF) in an AJAX action. This vulnerability allows authenticated users, including those with low-level roles like subscribers, to manipulate plugin options and grant themselves elevated privileges such as the ability to edit plugins. This presents a significant risk to WordPress sites using the plugin, as it can lead to unauthorized actions and compromise site integrity.
