CVE-2024-30927Public exploitNetwork attack vector

Unauthenticated script execution via unencoded racerid output

Published Apr 18, 2024 · Updated Nov 4, 2025

Reflected XSS in DerbyNet 9.0 and earlier allows remote attackers to execute JavaScript through a crafted racer-results.php URL. The page echoes the racerid query parameter into its HTML title element without context-appropriate output encoding, so a closing title tag can introduce a script element. Exploitation requires a victim to open the crafted URL, and the injected script runs in the DerbyNet site's browser context.
