Today, Apple has started rolling out iOS 14.4.2, iPadOS 14.4.2, and watchOS 7.3.3, and the company has advised users to upgrade as soon as possible. Like iOS / iPadOS 14.4.1 before, this update addresses a security issue.
In addition, Apple has released a similar security update – 12.5.2 – for older devices such as the iPhone 5S or 6 that cannot run iOS 14.
The release notes for iOS 14.4.2 and iPadOS 14.4.2 are minimal and simply state:

The same goes for the watchOS update. All four software updates (iOS 14.4.2, iPadOs 14.4.2, iOS 12.5.2, and watchOS 7.3.3) should already be available to all users of supported devices. This is the second update since the release of iOS / iPadOS 14.4 and watchOS 7.3 in late January.
The update that preceded this was also an urgent fix to a security issue.
iOS 14.4 was a feature update, not just a security update or bug fix, but the added features were relatively modest.
