How to fix?

Upgrade next-auth to version 3.29.8, 4.9.0 or higher.

Overview

next-auth is an Authentication for Next.js

Affected versions of this package are vulnerable to Improper Input Validation via the email sign-in endpoint, due to lack of sanitization. Exploiting this vulnerability allows an attacker to send an HTML payload that will be displayed on the verification email sent to the email address.

Workaround:

If for some reason you cannot upgrade versions, the workaround requires you to sanitize the email parameter that is passed to sendVerificationRequest and rendered in the HTML.
