      "value": "In Eclipse KUKSA Databroker version 0.6.1, the kuksa.val.v2.VAL/PublishValue gRPC handler fails to validate the existence of the optional data_point field in PublishValueRequest. When a request contains a valid signal_id but omits data_point, the server directly calls unwrap() on request.data_point, triggering a panic in the Tokio worker thread. This issue can be triggered by any client holding a valid JWT token. Unauthenticated or invalid-token requests are rejected and do not reach the vulnerable path. The panic causes the individual gRPC call to be cancelled but does not terminate the Databroker process, which remains available for subsequent requests."

      "value": "En Eclipse KUKSA Databroker versión 0.6.1, el gestor gRPC kuksa.val.v2.VAL/PublishValue no valida la existencia del campo opcional data_point en PublishValueRequest. Cuando una solicitud contiene un signal_id válido pero omite data_point, el servidor llama directamente a unwrap() en request.data_point, lo que desencadena un pánico en el hilo de trabajo de Tokio. Este problema puede ser provocado por cualquier cliente que posea un token JWT válido. Las solicitudes no autenticadas o con token inválido son rechazadas y no alcanzan la ruta vulnerable. El pánico provoca que la llamada gRPC individual sea cancelada, pero no termina el proceso de Databroker, el cual permanece disponible para solicitudes posteriores."
