Webcake – Landing Page Builder <= 1.1 - Missing Authorization to Authenticated (Subscriber+) Settings Update

The Webcake – Landing Page Builder plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'webcake_save_config' AJAX endpoint in all versions up to, and including, 1.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the plugin's settings.
