Input validation vulnerability in Ultimate XML Sitemaps Generator for Google 1.3.3

The XML Sitemap Generator for Google plugin for WordPress has a security issue in versions 1.3.3 and earlier. This means that someone who is not authorized to use the plugin could potentially change the settings without permission. This could happen if they can get a site administrator to do something like clicking on a link. The reason this is possible is because the plugin does not have the proper security measures in place to verify that the change is coming from an authorized user.
