## Technical details

The UserContext component in the GenAI web interface fails to validate the redirect destination URL taken from the NEXT_PUBLIC_LOGIN_URL configuration parameter before redirecting users to the login page. This allows an attacker to craft a malicious request that redirects a user to an arbitrary external domain during the session-handling flow. The vulnerability requires user interaction but can be exploited remotely via a phishing link.
