Does this matter?

Lower severity and a low EPSS score (1.51%). Track it; it rarely justifies an emergency change on its own.

Starting in version 14.0.0 and prior to versions 14.3.2 and 15.1.2, it's possible to determine whether an account exists based on an analysis of response codes and timing of Umbraco management API responses.
