Does this matter?

Lower severity and a low EPSS score (2.07%). Track it; it rarely justifies an emergency change on its own.

Description

An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles symlinks. An attacker who successfully exploited this vulnerability could delete files and folders in an elevated context. To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and delete files or folders of their choosing. The security update addresses the vulnerability by correcting how the Windows User Profile Service handles symlinks.
