Microsoft ASP.NET Core Security Feature Bypass Vulnerability

Details

A security feature bypass vulnerability exists in the way Microsoft ASP.NET Core parses encoded cookie names.

The security update addresses the vulnerability by fixing the way the ASP.NET Core cookie parser handles encoded names.
