### Overview Versions before and including `1.4.1` are vulnerable to reflected XSS. An attacker can execute arbitrary code by providing an XSS payload in the `error` query parameter which is then processed by the callback handler as an error message. ### Am I affected? You are affected by this vulnerability if you are using `@auth0/nextjs-auth0` version `1.4.1` or lower **unless** you are using custom error handling that does not return the error message in an HTML response. ### How to fix that? Upgrade to version `1.4.2`. ### Will this update impact my users? The fix adds basic HTML escaping to the error message and it should not impact your users. ### Credit https://github.com/inian https://github.com/git-ishanpatel
