How to fix?

Upgrade System.Net.Http to version 2.0.20710, 4.0.1-beta-23225, 4.1.4, 4.3.4 or higher.

Overview

System.Net.Http Provides a programming interface for modern HTTP applications, including HTTP client components that allow applications to consume web services over HTTP and HTTP components that can be used by both clients and servers for parsing HTTP headers.

Affected versions of this package are vulnerable to Information Exposure. When HTTP authentication information is inadvertently exposed in an outbound request that encounters an HTTP redirect. An attacker who successfully exploited this vulnerability could use the information to further compromise the web application.

Note: The presence of System.Net.Http in the dependency graph of netcoreapp2.0 isn't the final determination of what is loaded at runtime. The version conflict resolution logic will prefer what is present in Microsoft.NETCore.App/2.1.5, or the latest patch release. As such, is not considered an issue.
