Mitigation checklist
Recommended fix / mitigation
- To mitigate this issue, configure the `camel-undertow` consumer to explicitly set `muteException=true`. This can be done by adding `?muteException=true` to the consumer URI (e.g., `undertow:http://0.0.0.0:8080/api?muteException=true`) or by setting the global property `camel.component.undertow.mute-exception=true`. This prevents Java stack traces from being returned in HTTP responses upon route processing errors. Note that this workaround may not apply to Rest DSL consumers in affected releases. A restart of the application or service hosting the Camel Undertow component may be required for the changes to take effect.
