MEDIUM 4.8EPSS 0.18%

Does this matter?

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

Description

Attackers can deliver unsigned PowerShell scripts or modules in downloaded archives that run under the RemoteSigned policy when the user invokes them.
