The SimpleShop plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.10.0. This is due to missing or incorrect nonce validation on the maybedisconnectsimpleshop function. This makes it possible for unauthenticated attackers to disconnect the site from simpleshop via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
