How to fix?

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

Overview

Microsoft.AspNetCore.Mvc.Abstractions is abstractions and interfaces for action invocation and dispatching, authorization, action filters, formatters, model binding, routing, validation, and more.

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.
