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. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The PixelYourSite plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 11.1.5 through publicly exposed log files. This makes it possible for unauthenticated attackers to view potentially sensitive information contained in the exposed log files, when the "Meta API logs" setting is enabled (disabled by default). The vulnerability was partially patched in version 11.1.5 and fully patched in version 11.1.5.1.

The PixelYourSite – Your smart PIXEL (TAG) & API Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 11.1.2. This is due to missing or incorrect nonce validation on the adminEnableGdprAjax() function. This makes it possible for unauthenticated attackers to modify GDPR settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The PixelYourSite – Your smart PIXEL (TAG) & API Manager and the PixelYourSite PRO plugins for WordPress are vulnerable to Sensitive Information Exposure in all versions up to, and including, 9.7.1 and 10.4.2, respectively, through publicly exposed log files. This makes it possible for unauthenticated attackers to view potentially sensitive information contained in the exposed log files, and to delete log files.
