Overview
ghost is a publishing platform
Affected versions of this package are vulnerable to Session Fixation due to the createSessionForUser logic in ghost/core/core/server/services/auth/session/session-service.js. An attacker can reuse a pre-set session identifier by getting a victim to authenticate on the same Ghost Admin domain, causing the victim’s login to bind to an attacker-known session. This lets the attacker hijack the authenticated admin session after login and act as that user, exposing admin access and any data or actions available in Ghost Admin.
