Apple has just released security updates to bring macOS Golden Gate to 27.2.1, Tahoe to 26.7.3, and Sequoia to 15.8.3. I expect there will also be separate Safari updates for Tahoe and Sequoia.
The 27.2.1 update is around 3.33 GB in size.
Security release notes are due imminently at this page.
I will update this as and when I have more information.
