CVE ID : CVE-2025-55008

Published : Aug. 9, 2025, 3:15 a.m. | 16 minutes ago

Description : The AuthKit library for React Router 7+ provides helpers for authentication and session management using WorkOS & AuthKit with React Router. In versions 0.6.1 and below, @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. This issue is fixed in version 0.7.0.

Severity: 7.1 | HIGH
