next-auth v3 users before version 3.29.2 are impacted. next-auth version 4 users before version 4.3.2 are also impacted. Upgrading to 3.29.2 or 4.3.2 will patch this vulnerability. If you are not able to upgrade for any reason, you can add a configuration to your callbacks option. If you already have a redirect callback, make sure that you match the incoming url origin against the baseUrl.
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
