Microsoft is releasing this security advisory to provide information about a vulnerability in the ASP.NET Core project templates. This advisory also provides guidance on what developers can do to update their applications to address this vulnerability.

A Denial of Service vulnerability exists in ASP.NET Core project templates which utilize JWT-based authentication tokens. This vulnerability allows an unauthenticated client to consume arbitrarily large amounts of server memory, potentially triggering an out-of-memory condition on the server and making the server no longer able to respond to legitimate requests.
