AI-suggested
Administrators should delete the default 'root' user after creating other users to mitigate the risk. Alternatively, configure the initial root password via an environment variable or configuration file as a temporary workaround to avoid using the default weak password.
Description
Vantage6 versions prior to 5.0.0 create an initial administrative user with a default username 'root' and password 'root'. This default credential is weak and widely known, increasing the risk that attackers could gain administrative access if the password is not changed. A temporary mitigation includes setting the initial root password via an environment variable or configuration file to avoid using the default password.
