CVE-2025-67716  (opens in a new tab)
CWE-184  (opens in a new tab)

How to fix?

Upgrade @auth0/nextjs-auth0 to version 4.13.0 or higher.

Overview

@auth0/nextjs-auth0 is a Next.js SDK for signing in with Auth0

Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via improper validation of the returnTo parameter. An attacker can cause tokens to be issued with unintended parameters by injecting unauthorized OAuth query parameters into the authorization request.

Note:

This is only exploitable if the application uses the affected SDK versions and processes user-controlled returnTo values.
