The Auto Post Scheduler plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.84. This is due to missing nonce validation on the 'aps_options_page' function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
