What the vulnerability does
01Description
The Google Plus One Bottom plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.0.2. This is due to missing or incorrect nonce validation on the googlePlusOneAdmin function. This makes it possible for unauthenticated attackers to modify the plugin's settings, including the plusone-lang, plusone-callback, and plusone-url options stored in the database via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
