No affected components available
In versions before 0.7.0, @workos-inc/authkit-react-router exposed sensitive authentication artifacts — specifically sealedSession and accessToken by returning them from the authkitLoader. This caused them to be rendered into the browser HTML.
Impact
This information disclosure could lead to session hijacking in environments where cross-site scripting (XSS), malicious browser extensions, or local inspection is possible.

In patched versions:
sealedSessionandaccessTokenare no longer returned by default from theauthkitLoader.- A secure server-side mechanism is provided to fetch an access token as needed.
