## Overview

Omnispace Agora Project before 26.10.0 contains a session fixation vulnerability that allows remote attackers to hijack authenticated sessions by planting a known session identifier in a victim's browser prior to login. Attackers can exploit the application's failure to regenerate the session id upon successful authentication to gain unauthorized access to the victim's authenticated session after they log in.
