Technical details
An information disclosure vulnerability exists in @angular/common when Server-Side Rendering (SSR) and hydration are enabled. The HttpTransferCache utility fails to inspect the 'withCredentials' flag or 'Cookie' headers of outgoing HTTP requests performed during SSR. Consequently, user-specific responses containing sensitive data may be cached in the shared TransferState payload and serialized into the HTML. If the application is behind a shared caching layer (like a CDN or reverse proxy) that does not distinguish between authenticated sessions, one user's private data can be served to subsequent users. This is fixed in versions 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23.
