CVE-2024-41810Public exploitNetwork attack vector

Reflected XSS via unescaped redirect URL

Published Jul 29, 2024 · Updated Nov 3, 2025

Reflected XSS in Twisted 24.3.0 and earlier allows remote attackers to run scripts in a victim's Firefox session via a crafted redirect URL. The redirectTo function interpolates its URL argument into the HTTP 302 fallback response body without HTML escaping. Exploitation requires application code to expose attacker control over the redirect target and a victim to open it in Firefox, enabling actions in that session.
