Description
Overview
Versions before and including 11.25.1 are using dangerouslySetInnerHTML to display an informational message when used with a Passwordless or Enterprise connection.
- For Passwordless connection, the value of the input (email or phone number) is displayed back to the user while waiting for verification code input.
- For Enterprise connection, the value of the input (IdP Domain) from the Enterprise connection setup screen (Auth0 Dashboard) is displayed back to the user when the
lock widget opens.
When Passwordless or Enterprise connection is used, the application and its users might be exposed to cross-site scripting (XSS) attacks.
