Sensitive information sent insecurely In @workos-inc/authkit-react-router
Description
The AuthKit React Router Library rendered sensitive auth data in HTML
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.
Patches
Patched in https://github.com/workos/authkit-react-router/releases/tag/v0.7.0
In patched versions:
sealedSession and accessToken are no longer returned by default from the authkitLoader.
A secure server-side mechanism is provided to fetch an access token as needed.
Mitigation
Update Impact
Minimal update. May introduce new vulnerabilities or breaking changes.
