      "value": "Duende.AccessTokenManagement.OpenIdConnect is a set of .NET libraries that manage OAuth and OpenId Connect access tokens. HTTP Clients created by `AddUserAccessTokenHttpClient` may use a different user's access token after a token refresh occurs. This occurs because a refreshed token will be captured in pooled `HttpClient` instances, which may be used by a different user. Instead of using `AddUserAccessTokenHttpClient` to create an `HttpClient` that automatically adds a managed token to outgoing requests, you can use the `HttpConext.GetUserAccessTokenAsync` extension method or the `IUserTokenManagementService.GetAccessTokenAsync` method. This issue is fixed in Duende.AccessTokenManagement.OpenIdConnect 3.0.1. All users are advised to upgrade. There are no known workarounds for this vulnerability."

Los clientes HTTP creados por `AddUserAccessTokenHttpClient` pueden usar el token de acceso de un usuario diferente después de que se actualice el token. Esto ocurre porque un token actualizado se capturará en instancias `HttpClient` agrupadas, que pueden ser utilizadas por un usuario diferente. En lugar de usar `AddUserAccessTokenHttpClient` para crear un `HttpClient` que agregue automáticamente un token administrado a las solicitudes salientes, puede usar el método de extensión `HttpConext.GetUserAccessTokenAsync` o el método `IUserTokenManagementService.GetAccessTokenAsync`. Este problema se solucionó en Duende.AccessTokenManagement.OpenIdConnect 3.0.1. Se recomienda a todos los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."
