Session hijacking via retained pre-authentication session identifier
Published Jan 28, 2026 · Updated Jan 28, 2026
Session fixation in AltumCode 66biolinks 62.0.0 allows remote attackers to hijack authenticated sessions via a fixed session ID. After successful authentication, the login flow retains the pre-authentication session identifier instead of issuing a new value, leaving the browser on an attacker-known cookie. Exploitation requires the attacker to set or predict the victim's session ID before login; successful replay grants the victim's authenticated access without the credentials.
