Overview

Microsoft.AspNetCore.Mvc.Core contains common action result types, attribute routing, application model conventions, API explorer, application parts, filters, formatters, model binding, 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.
