Input validation vulnerability in Simple Post 1.1

The Simple Post plugin for WordPress is not secure in versions up to, and including, 1.1. This means that if someone with malicious intent were to gain access to the plugin, they could inject code into the pages. This code would then be executed whenever someone views the page, potentially allowing the malicious user to steal information or access data they should not have access to. To protect against this vulnerability, users should make sure to update to the latest version of the plugin.
