| Description | Client-set push config URLs were POSTed to by the server without any validation, so a caller who can create a push notification config can point the server at loopback, private-network, link-local, or cloud-metadata hosts.
In src/a2a/server/tasks/base_push_notification_sender.py, _dispatch_notification passes push_info.url straight to self._client.post(url, ...) — the URL comes from a TaskPushNotificationConfig that callers can create, and no scheme or IP checks exist before the request is sent. |
