Upgrade System.Formats.Nrbf to version 9.0.0 or higher.
Overview
System.Formats.Nrbf is a package that exposes only one component: NrbfDecoder: a stateless, forward-only decoder class that can decode .NET Remoting Binary Format (NRBF) binary data from a stream.
Affected versions of this package are vulnerable to Access of Resource Using Incompatible Type ('Type Confusion') through the NrbfDecoder component. An attacker can execute arbitrary code by sending specially crafted requests to a vulnerable .NET web application or loading a specially crafted file into an application.
Note:
By default, .NET console apps and web apps do not reference the NrbfDecoder component.
