Ghost 6.20.0 before 6.57.1 Authentication Bypass via Session Handling
Ghost versions 6.20.0 before 6.57.1 contain a session handling vulnerability that allows authenticated staff users to log in as any other staff user with only the password, bypassing two-factor authentication. Attackers with valid staff credentials can exploit improper session management to impersonate other staff members and gain unauthorized access to administrative functions.
