Description

The Keybase.io Verification plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.5. This is due to missing nonce validation when updating plugin settings. This makes it possible for unauthenticated attackers to update the Keybase verification text via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
