Detailed vulnerability description
The vulnerability allows a remote attacker to redirect users to an attacker-controlled site.
The vulnerability exists due to url redirection to an untrusted site in the /login endpoint when processing a crafted next parameter using basic-auth userinfo syntax. A remote attacker can supply a specially crafted next value to redirect users to an attacker-controlled site.
User interaction is required because the victim must complete the login flow before the client-side redirect occurs.
