Quicksand Post Filter jQuery Plugin <= 3.1.1 - Cross-Site Request Forgery via renderAdmin

Description

The Quicksand Post Filter jQuery Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.1.1. This is due to missing or incorrect nonce validation on the 'renderAdmin' function. This makes it possible for unauthenticated attackers to update arbitrary site options via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
