ElementsKit Elementor Addons <= 3.8.2 - Missing Authorization to Unauthenticated Widget Content Overwrite

Summary

The ElementsKit Elementor Addons plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `Live_Action::reset()` function in all versions up to, and including, 3.8.2 The function is hooked to the WordPress `init` action and triggers when both `post` and `action=elementor` GET parameters are present, with no authentication or nonce verification. This makes it possible for unauthenticated attackers to overwrite the Elementor content (`_elementor_data`) of any `elementskit_widget` custom post type by visiting a specially crafted URL. The widget's custom designs, text, and configurations are permanently replaced with a blank template.
