What the vulnerability does
The PixelYourSite PRO 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, 12.4.0.2 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.
Explanation of Vulnerability in Simple Terms
PixelYourSite Pro versions up to 12.4.0.2 contain a cross-site scripting vulnerability that allows attackers to inject malicious scripts into the site without authentication. The vulnerability affects the scope beyond the vulnerable component, potentially impacting other parts of the application. Site administrators should update to a version newer than 12.4.0.2 to remediate this issue.
What an attacker can do
Inject malicious JavaScript that executes in visitors' browsers and affects other site functionality.
Potential impact on your site
Visitors' browsers may execute attacker-controlled scripts, potentially stealing data or modifying site behavior.
