Description

A flaw was found in Angular. When Server-Side Rendering (SSR) and hydration are used with a hierarchical HttpClient configured with `withRequestsMadeViaParent`, the `HttpTransferCache` can improperly cache authenticated responses. This occurs because a child TransferCache stores private response data in TransferState even when a parent HttpClient chain adds credentials and skips the authenticated request. Consequently, a later unauthenticated or unauthorized visitor could receive cached HTML containing sensitive data from a previously authenticated user, leading to information disclosure.
