### Summary The implementation did not validate the legitimacy of the `email` attribute of the user nor did it give/document an option to do so, making it susceptible to [nOAuth](https://www.descope.com/blog/post/noauth) misconfiguration in cases when the `email` is used as a trusted user identifier
