Vulnerability details
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data in the Node.js adapter when forwarding requests to Keycloak using checkSSO with query param 'prompt=none'. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
