CVE-2022-29172 Information

Description

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 fieldsâ€? 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 fieldsâ€? feature in your application. Upgrade to version 11.33.0.
