The Web and WooCommerce Addons for WPBakery Builder plugin for WordPress is vulnerable to unauthorized plugin settings modification due to a missing capability check on several plugin functions in all versions up to, and including, 1.4.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change some of the plugin settings.
