I installed a CH from debian repos (just copied from docs) and installation process asking me for a password, I typed my testing password ended by "();" witouth quotes.

After install I can access without any password.

users.xml show like "<password></password>" for default user.

¯\\\_(ツ)\_/¯

"        </default>\n"
                    "    </users>\n"
                    "</yandex>\n";
                out.sync();
                out.finalize();
                fmt::print("Password for default user is saved in file {}.\n", password_file);
#else
                out << "<yandex>\n"
                    "    <users>\n"
                    "        <default>\n"
                    "            <password><![CDATA[" << password << "]]></password>\n"
                    "        </default>\n"
                    "    </users>\n"
                    "</yandex>\n";
                out.sync();
                out.finalize();
                fmt::print("Password for default user is saved in plaintext in file {}.\n", password_file);
#endif
                has_password_for_default_user = true;
            }
            else
                fmt::print("Password for default user is empty string. See {} and {} to change it.\n",
