CVE-2026-46592
Apache Camel: Camel-CXF: The SOAP operation-selection headers used non-Camel-prefixed names (operationName, operationNamespace) that bypass the HTTP header filter, allowing an HTTP client to redirect the invoked SOAP operation
Description
Improper Input Validation, Unintended Proxy or Intermediary ('Confused Deputy') vulnerability in Apache Camel CXF SOAP component. The camel-cxf producer selects which SOAP operation to invoke on the backend service from the operationName (and operationNamespace) Exchange header, whose constant values (CxfConstants.OPERATION_NAME / OPERATION_NAMESPACE) were the plain strings operationName / operationNamespace. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into a cxf: producer, any HTTP client could therefore set the operationName header and have CxfProducer resolve and invoke a different WSDL operation than the route intended - for example replacing a read operation with a destructive one - against the backend SOAP service (a confused-deputy redirection). The constant is defined in the shared camel-cxf-common module, so the same non-prefixed names also applied to camel-cxfrs. No credentials are required when the bridging consumer is unauthenticated. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, the operation-selection headers are named CamelCxfOperationName / CamelCxfOperationNamespace and are filtered at transport boundaries; see the 4.21 upgrade guide for the cross-transport carrier-header pattern. For deployments that cannot upgrade immediately, do not select the CXF operation from untrusted input: strip the operationName and operationNamespace headers from any untrusted ingress before the cxf: producer and set the operation from a trusted source in the route.

Action Type Old Value New Value Added Translation Title: Apache Camel de Apache Software Foundation, Description: Validación de entrada incorrecta, vulnerabilidad de Proxy o Intermediario no intencionado (’Delegado Confundido’) en el componente SOAP de Apache Camel CXF. El productor camel-cxf selecciona qué operación SOAP invocar en el servicio de backend desde el encabezado Exchange operationName (y operationNamespace), cuyos valores constantes (CxfConstants.OPERATION_NAME / OPERATION_NAMESPACE) eran las cadenas simples operationName / operationNamespace. Debido a que estos nombres no comienzan con el prefijo Camel / camel, HttpHeaderFilterStrategy - que bloquea solo el espacio de nombres del encabezado Camel en el límite HTTP - los dejó pasar de una solicitud HTTP entrante directamente al Exchange. En una ruta que conecta un consumidor HTTP (por ejemplo, platform-http) con un productor cxf:, cualquier cliente HTTP podría, por lo tanto, establecer el encabezado operationName y hacer que CxfProducer resuelva e invoque una operación WSDL diferente a la que la ruta pretendía - por ejemplo, reemplazando una operación de lectura por una destructiva - contra el servicio SOAP de backend (una redirección de delegado confundido). La constante está definida en el módulo compartido camel-cxf-common, por lo que los mismos nombres sin prefijo también se aplicaron a camel-cxfrs. No se requieren credenciales cuando el consumidor de conexión no está autenticado. Este problema afecta a Apache Camel: desde 4.0.0 antes de 4.14.8, desde 4.15.0 antes de 4.18.3, desde 4.19.0 antes de 4.21.0. Se recomienda a los usuarios actualizar a la versión 4.21.0, que corrige el problema. Si los usuarios están en la rama de versiones LTS 4.14.x, se sugiere que actualicen a 4.14.8. Si los usuarios están en la rama de versiones 4.18.x, se sugiere que actualicen a 4.18.3. Después de actualizar, los encabezados de selección de operación se denominan CamelCxfOperationName / CamelCxfOperationNamespace y se filtran en los límites de transporte; consulte la guía de actualización 4.21 para el patrón de encabezado portador entre transportes. Para implementaciones que no pueden actualizarse inmediatamente, no seleccione la operación CXF de entrada no confiable: elimine los encabezados operationName y operationNamespace de cualquier entrada no confiable antes del productor cxf: y establezca la operación desde una fuente confiable en la ruta. -
