NextMove Lite < 2.18.2 - Cross-Site Request Forgery

Description The NextMove Lite plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.18.1. This is due to missing or incorrect nonce validation on the xl_addon_installation() function. This makes it possible for unauthenticated attackers to install addons via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
