How to fix?

Upgrade System.Net.Security to version 4.0.1, 4.3.1 or higher.

Overview

System.Net.Security provides types, such as System.Net.Security.SslStream, that uses SSL/TLS protocols to provide secure network communication between client and server endpoints.

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.
