Events Addon for Elementor < 2.1.3 - Cross-Site Request Forgery

Description

The plugin is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.2. This is due to missing nonce validation on the naevents_bw_settings_save_func(), naevents_bw_toggle_submit_func(), naevents_pro_settings_save_func(), naevents_pro_toggle_submit_func() and naevents_uw_settings_save_func() functions. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
