Session Management Flaw in Ghost by TryGhost Allows Unauthorized User Impersonation

CVE-2026-103283

What is CVE-2026-103283?

Ghost versions prior to 6.57.1 exhibit a vulnerability related to session handling that allows authenticated staff users to log in as any other staff user using just their password. This undermines the effectiveness of two-factor authentication, making it possible for attackers with valid staff credentials to exploit weaknesses in session management. Consequently, these users can impersonate other staff members and gain unauthorized access to sensitive administrative functions, posing a significant security risk.
