Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

A flaw in Portal for ArcGIS allows unauthenticated users to create new accounts through the sharing endpoint even when self-service account registration is disabled (disableSignup=true). An attacker can bypass the intended restriction by manipulating the signup workflow, resulting in unauthorized account creation.
