macOS Golden Gate includes bug fixes and security updates, according to Apple's release notes. The update likely includes a fix to prevent command-line tools from accepting eMudhra's compromised web certificates.
Apple already blocked the compromised certificates on October 19, so most users are already protected.
You can download macOS Golden Gate 27.2.1 over the air through the Software Update section of the System Settings app.
