Summary

When a username for an Active Directory connection is a domain without a local part, the auth0-lock library initiates the authentication transaction with a GET request instead of a POST request. As a result, user-submitted form data is appended to the URL as query string parameters.

Risk Assessment

Authentication data or other sensitive information may be exposed in the URL, potentially leading to interception by third parties (e.g., in server logs, browser history).

Recommendation

It is recommended to upgrade the auth0-lock library to a version that uses the POST method in such cases, and avoid using usernames that are just a domain.
