Summary
jupyter_server next parameter open redirect can redirect users to external domains
Details

Jupyter Server is the backend for Jupyter web applications. In jupyter_server versions through 2.17.0, the next query parameter in the login flow is insufficiently validated in LoginFormHandler._redirect_safe(), which allows redirects to arbitrary external domains via values such as ///example.com. An attacker can use a crafted login URL to redirect users to a malicious site and facilitate phishing attacks. This issue is fixed in version 2.18.0.
