How to Fix CVE-2026-84180

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-84180, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-209: Generation of Error Message Containing Sensitive Information, where the product generates an error message that includes sensitive information about its environment, users, or associated data. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
