CVE-2025-55009: The AuthKit Remix Library renders sensitive auth data in HTML
(updated )
In versions before 0.15.0, @workos-inc/authkit-remix exposed sensitive authentication artifacts — specifically sealedSession and accessToken — by returning them from the authkitLoader. This caused them to be rendered into the browser HTML.
