Overview
ghost is a publishing platform
Affected versions of this package are vulnerable to Insufficient Session Expiration via the isVerifiedSession function in session-service.js, where session verification state is not bound to a specific user identity. When a session's verified flag is set without an associated verified_user_id, the check session.verified_user_id === session.user_id resolves to undefined === undefined, evaluating to true and incorrectly granting verified status to any user inheriting that session. An authenticated attacker can exploit this to bypass staff device verification and gain unauthorized access to privileged functionality.
