We've just been alerted that this update fixes a security vulnerability:

Sourced from The GitHub Security Advisory Database.

Low severity vulnerability that affects react-dom
React applications which rendered to HTML using the ReactDOMServer API were not escaping user-supplied attribute names at render-time. That lack of escaping could lead to a cross-site scripting vulnerability. This vulnerability can only affect some server-rendered React apps. Purely client-rendered apps are not affected.

This issue affected minor releases 16.0.x, 16.1.x, 16.2.x, 16.3.x, and 16.4.x. It was fixed in 16.0.1, 16.1.2, 16.2.1, 16.3.3, and 16.4.2.

Affected versions: [">= 16.4.0 < 16.4.2"]
