The PixelYourSite – Your smart PIXEL (TAG) & API Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'pysTrafficSource' parameter and the 'pys_landing_page' parameter in all versions up to, and including, 11.2.0 due to insufficient input sanitization and output escaping.
