The Team Circle Image Slider With Lightbox plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘search_term’ parameter in versions up to, and including, 1.0.17 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
The Team Circle Image Slider With Lightbox WordPress plugin before 1.0.16 does not sanitize and escape the order_pos parameter before outputting it back in an admin page, leading to a Reflected Cross-Site Scripting.
