Update (2023-02-21): Howard Oakley:
A small minority of users experienced something strange when they updated to macOS 13.2.1, or even 13.2. Instead of the updated macOS automatically returning them to the Finder and Desktop once the update was complete, it bounced the Mac into Recovery (or similar, if your Mac is managed) and asked for the password. This article explains what happened, and other accidents that can happen when updates don’t work right.
For macOS Big Sur and macOS Ventura Apple has released what they publicly call Safari 16.3.1 to address the WebKit vulnerability. Unfortunately the version number in the About Safari window and app bundle's CFBundleShortVersionString remains the same "16.3" as the previous release. To identify the new version you have to look at the build number in the About Safari window or the app bundle's CFBundleVersion which represents the build number. Sadly this is at least the 3rd time Apple has released a security update to Safari which retains the same version number as the previous release but updates the build number.
