Omnispace Agora Project before 26.10.0 contains an authentication bypass vulnerability that allows attackers possessing a user's stored bcrypt password hash to authenticate as that user without knowing the actual password, caused by the legacy AGORAP_LOG/AGORAP_PASS cookie mechanism treating the stored hash as a directly replayable bearer credential. Attackers can set the AGORAP_LOG/AGORAP_PASS cookies with a stolen password hash to impersonate any user, including administrators, and gain unauthorized access to the application.
