description
Affected ASP.NET Core runtime packages can mishandle header-count enforcement while processing multipart form requests. An unauthenticated remote attacker may consume server resources and disrupt service by reaching an application endpoint that accepts multipart form data.
mitigation
Update affected ASP.NET Core packages or runtimes to 8.0.34, 9.0.23, 10.0.15, or 11.0.0, as appropriate for the deployment. Until updates are complete, restrict access to endpoints that accept multipart form uploads and apply request-size and rate limits at the edge.
fixed in 8.0.34, 9.0.23, 10.0.15, 11.0.0
