CVE-2021-32702: Security Update for Auth0 Next.js Library
Published: June 23, 2021
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
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
Will this update impact my users?
The fix adds basic HTML escaping to the error message and it should not impact your users.
