Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict the affected network interface to trusted sources where business-safe.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Apache Software Foundation Apache Camel and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

CVE-2026-46592 · CSAF 2.0 · revision 3 · finalRed Hat Product Securityorg.apache.camel/camel-cxf: Apache Camel CXF SOAP: Remote attacker can execute unintended operations via header manipulation
The vendor explicitly identifies these products as affected by this CVE.
- camel-cxf-common as a component of Red Hat build of Apache Camel 4 for Quarkus 3
- Summary
- A flaw was found in the Apache Camel CXF SOAP component. A remote attacker can exploit this vulnerability by manipulating the `operationName` header in an unauthenticated HTTP request. This improper input validation allows the attacker to force the `CxfProducer` to invoke unintended SOAP operations on the backend service. This could lead to a 'confused deputy' scenario, where a read operation is replaced with a destructive one, impacting the integrity of the backend service.
- Remediation
- Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258

Patch available01
What, why and how
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.

Why
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
