CVE ID: CVE-2024-30927  
A Cross-Site Scripting (XSS) vulnerability is present in DerbyNet version 9.0, specifically within the `racer-results.php` component. This issue allows remote attackers to execute arbitrary code through the improper handling of the `racerid` parameter. The vulnerability is notably present within the HTML `<title>` tag, where the `racerid` parameter value is dynamically inserted directly into the page content without any sanitization or encoding.
