Description
The Subscribe to Comments plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.3.2 due to missing nonce validation on the subscription manager's actions. This makes it possible for unauthenticated attackers to remove any subscriber's comment subscriptions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
