Details

Cross-site Scripting in Auth0 Lock ### Overview In versions before and including `11.32.2`, when the “additional signup fields” feature [is configured](https://github.com/auth0/lock#additional-sign-up-fields), 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. ### Am I affected? 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. ### How to fix that? Upgrade to version `11.33.0`. ### Will this update impact my users? Additional signup fields that have been added to the signup tab on Lock will have HTML tags stripped from user input from version `11.33.0` onwards. The user will not receive any validation warning or feedback, but backend data will no longer include HTML.
