auth0-lock@6.2.21 vulnerabilities

auth0-lock is a plugin for Auth0.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) when the “additional signup fields” feature is configured, allowing a malicious actor to 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.

auth0-lock is an authentication broker that supports both social and enterprise identity providers, including Active Directory, LDAP, Google Apps, and Salesforce.

Affected versions of this package are vulnerable to Cross-Site Request Forgery (CSRF) attacks if the Legacy Lock API flag is enabled.

Once the user credentials are verified, an HTML form is rendered into the user’s browser. A JSON Web Token (JWT) is POSTed to the /login/callback endpoint, and it maintains state regarding the identity of the user. Due to the lack of session binding, this form post is susceptible to CSRF. An attacker with valid user credentials at an Auth0 tenant can use them to gain such a form, and then employ techniques such as social engineering or clickjacking to have a victim’s browser execute it.

Upgrade auth0-lock to version 11.0.0 or higher.
