Publish 2 Ping.fm <= 1.1 - Cross-Site Request Forgery to Stored Cross-Site Scripting via 'wpPingPingKey' Parameter

The Publish 2 Ping.fm plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1. This is due to missing or incorrect nonce validation on the '/wp-admin/options-general.php?page=admin.php' page. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
