Simple calendar for Elementor <= 1.6.5 is vulnerable to Cross Site Request Forgery (CSRF) Vulnerability

The Simple calendar for Elementor plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.6.5. This is due to missing or incorrect nonce validation on the miga_ajax_editor_cal_delete() and miga_ajax_editor_cal_update() functions. This makes it possible for unauthenticated attackers to edit and delate calendar data via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
