Does this matter?
Lower severity and a low EPSS score (1.07%). Track it; it rarely justifies an emergency change on its own.

A malicious user with enough information about the environment could jeopardize an environment with this specific Dynamic Client Registration and TrustedDomain configuration previously unauthorized.
