This affects the function _dispatch_notification of the file src/a2a/server/tasks/base_push_notification_sender.py of the component Push Notification Sender. The manipulation of the argument push_info.url leads to server-side request forgery. Remote exploitation of the attack is possible. Upgrading to version 1.1.4 is able to mitigate this issue. It is suggested to upgrade the affected component."
