The Cool Timeline (Horizontal & Vertical Timeline) plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.0.2. This is due to missing or incorrect nonce validation on the ctl_save() function. This makes it possible for unauthenticated attackers to save field icons via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Several WordPress plugins developed by Cool Plugins are vulnerable to arbitrary plugin installation and activation that can lead to remote code execution by authenticated attackers with minimal permissions, such as a subscriber.
