Description

Omnispace Agora Project before 26.10.0 contains an insecure randomness vulnerability that allows attackers to predict temporary or default account passwords generated by Txt::defaultPassword() using PHP's uniqid() function based on server time in microseconds. Attackers who observe or approximate the account creation time can compute the predictable password and take over the account before the legitimate user logs in.
