CWE-20  (opens in a new tab)

How to fix?

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

Overview

Microsoft.AspNetCore.Mvc.ViewFeatures contains common types used in most MVC applications as well as view rendering features such as view engines, views, view components, and HTML helpers.

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.
