| Descrizione | BasePushNotificationSender.dispatchNotification built the Authorization header as scheme + " " + credentials with direct string concatenation. Both values are client-controlled (stored in the push notification config), so a credential or scheme containing \r/\n could inject arbitrary extra headers (CWE-113). The JDK HttpClient happens to validate headers, but A2AHttpClient is a pluggable SPI whose implementations (including custom ones) cannot be assumed to do the same. |
