Online Booking & Scheduling Calendar for WordPress by vcita < 4.5.2 - Cross-Site Request Forgery

Description

The Online Booking & Scheduling Calendar for WordPress by vcita plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.5. This is due to missing or incorrect nonce validation on the vcita_save_settings_callback() function. This makes it possible for unauthenticated attackers to save settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
