How to fix?

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

Overview

Microsoft.AspNetCore.Mvc.ApiExplorer is the explorer functionality for discovering metadata such as the list of controllers and actions, and their URLs and allowed HTTP methods.

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.
