Summary
Omnispace Agora Project before 26.10.0 uses predictable values to generate temporary or default account passwords. The Txt::defaultPassword() function derives each password from PHP's uniqid() function, which is based on server time in microseconds, a flaw tracked as CWE-330. A remote attacker who observes or approximates the account creation time can compute the password and take over the account before the legitimate user logs in, without authentication.
