CVE-2026-107370

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.

MEDIUM 5.3EPSS 0.28%

Does this matter?

Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.

Description

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.
