Description

The auth0/nextjs-auth0 SDK validates that the returnTo parameter is a same-origin URL. The SDK then stores this value and, in a later step, reconstructs it for the post-authentication redirect. The reconstruction logic can produce a URL that browsers interpret as an absolute or scheme-relative path, leading to a redirect to an unintended domain.
