An external caller able to provoke a failure could therefore read internal detail about the deployment - class and package names, and whatever the exception message carries. Declared faults, annotated @WebFault, are a different matter: those are part of the published contract that clients are written against, and suppressing them would break the service rather than protect anything.\n\nUpgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. A muteException consumer option, defaulting to true, replaces an undeclared route failure with a generic fault carrying no class name, message or stack trace. Faults the contract declares are reported exactly as before. Set muteException=false to restore the previous output. For deployments that cannot upgrade immediately, declare the exceptions the service is allowed to report and map every other failure onto one of them in an onException handler, so no undeclared exception reaches the fault.\n\n## Affected\n\n- `org.apache.camel:camel-cxf >= 4.0.0 < 4.18.5`\n- `org.apache.camel:camel-cxf >= 4.19.0 < 4.22.1`\n\n## Remediation\n\nUpgrade to Apache Camel 4.23.0, which fixes the issue.
