Auth0 is an authentication broker that supports both social and enterprise identity providers, including Active Directory, LDAP, Google Apps, and Salesforce. In versions before 11.33.0
, when the “additional signup fields” feature is configured, a malicious actor can inject invalidated HTML code into these additional fields, which is then stored in the service user_metdata
payload (using the name
property). Verification emails, when applicable, are generated using this metadata. It is therefor possible for an actor to craft a malicious link by injecting HTML, which is then rendered as the recipient’s name within the delivered email template. You are impacted by this vulnerability if you are using auth0-lock
version 11.32.2
or lower and are using the “additional signup fields” feature in your application. Upgrade to version 11.33.0
.
