The AuthKit library for Remix provides convenient helpers for authentication and session management using WorkOS & AuthKit with Remix. In versions 0.14.1 and below, @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.
