Find And Replace content for WordPress <= 1.1 - Missing Authorization to Unauthenticated Stored Cross-Site Scripting

The Find And Replace content for WordPress plugin for WordPress is vulnerable to unauthorized Stored Cross-Site Scripting and Arbitrary Content Replacement due to a missing capability check on the far_admin_ajax_fun() function in all versions up to, and including, 1.1. This makes it possible for unauthenticated attackers to inject arbitrary web scripts into pages that can make privilege escalation and malicious redirects possible.
