How to fix?

Upgrade Microsoft.AspNetCore.Mvc.WebApiCompatShim to version 1.0.4, 1.1.3 or higher.

Overview

Microsoft.AspNetCore.Mvc.WebApiCompatShim provides compatibility in ASP.NET Core MVC with ASP.NET Web API 2 to simplify migration of existing Web API implementations.

Affected versions of this package are vulnerable to Authentication Bypass attacks. The ASP.NET Core fails to properly sanitize the Web Request Handler component, allowing an attacker to spoof web requests and bypass authentication.
