Description

The Schedule Posts Calendar plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.2. This is due to missing nonce validation on the schedule_posts_calendar_admin_page() function. 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.
