Upgrade Microsoft.AspNetCore.App.Runtime.win-x86 to version 11.0.0 or higher.
Overview
Microsoft.AspNetCore.App.Runtime.win-x86 is a package providing a default set of APIs for building an ASP.NET Core application. Contains assets used for self-contained deployments.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in its static server-side rendering client validation, which retains attacker-controlled rendered field names in an unbounded singleton cache. An attacker can exhaust server memory by submitting requests with many distinct field names that accumulate in the cache without eviction. This requires a Blazor app using static SSR with client-side validation.
