CVE-2026-84180— Apache Camel: Camel-Knative Information Disclosure via Unmuted Consumer Exceptions

Quick assessment

Affected
Apache Software Foundation Apache Camel
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Camel Knative 组件存在“错误消息中包含敏感信息”的漏洞。 该问题影响 Apache Camel 以下版本范围： 4.0.0 至 4.18.5（不含 4.18.5） 4.19.0 至 4.22.1（不含 4.22.1） 当消费者端处理交换（exchange）失败时，Knative HTTP 消费者会将产生的异常信息（包括异常类名、错误消息和堆栈跟踪）直接写入响应体并返回给远程调用方。外部攻击者因此可故意触发失败，从而获取部署的内部细节，例如：类名和包名、异常消息中携带的文件系统路径或主机名

Vulnerability Title
Apache Camel: Camel-Knative Information Disclosure via Unmuted Consumer Exceptions
Source: CVE Program / CVE List V5
Vulnerability Description
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Knative component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When processing of an exchange failed on the consumer side, the Knative HTTP consumer wrote the resulting exception back to the remote caller as the response body, including its class name, message and stack trace. An external sender could therefore provoke a failure and read internal detail about the deployment: class and package names, file system or host names carried in exception messages, and the shape of the route. That detail is useful for building a more targeted attack, and where an exception message embeds configuration or connection strings it is disclosure in its own right. camel-knative was the remaining HTTP-family consumer that had not been aligned with the muteException behaviour established for the other HTTP consumers by CAMEL-23651. Upgrade 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. The consumer now honours a muteException option that defaults to true, so a route failure returns an empty body with the error status rather than the exception. Set muteException=false to restore the previous output. For deployments that cannot upgrade immediately, add an onException handler that sets the response body explicitly, so that the framework never writes the exception back to the caller.
