Summary

Omnispace Agora Project before 26.10.0 contains a session fixation flaw (CWE-384) because the application does not regenerate the session identifier after a successful login. A remote attacker can plant a known session identifier in a victim's browser before login and then use it to access the victim's authenticated session after the victim logs in. The attack requires the victim to take an active step in the browser.
