Description

The Index Now plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.6.3. This is due to missing or incorrect nonce validation on the 'reset_form' function. This makes it possible for unauthenticated attackers to delete arbitrary site options via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
