WIP Incoming Lite <= 1.1.1 - Cross-Site Request Forgery to Stored Cross-Site Scripting

The WIP Incoming Lite plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.1. This is due to missing or incorrect nonce validation on the save_option() function. 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.
