CVE-2023-3204: materialis Auth Bypass — Fix

Description

The Materialis theme for WordPress is vulnerable to limited arbitrary options updates in versions up to, and including, 1.1.24. This is due to missing authorization checks on the companion_disable_popup() function called via an AJAX action. This makes it possible for authenticated attackers, with minimal permissions such as subscribers, to modify any option on the site to a numerical value.
