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.\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. 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.","state":0,"publishedAt":"2026-10-19T10:31:08.913+00:00","modifiedAt":"2026-10-19T18:35:59.978+00:00","affected":[{"ecosystem":"https://repo.maven.apache.org/maven2","name":"org.apache.camel:camel-knative","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Camel\",\n                    \"collectionURL\": \"https://repo.maven.apache.org/maven2\",\n                    \"packageName\": \"org.apache.camel:camel-knative\",\n                    \"packageURL\": \"pkg:maven/org.apache.camel/camel-knative\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.0.0\",\n                            \"lessThan\": \"4.18.5\",\n                            \"versionType\": \"maven\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.19.0\",\n                            \"lessThan\": \"4.22.1\",\n                            \"versionType\": \"maven\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"4.18.5\",\n                            \"versionType\": \"maven\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"4.22.1\",\n                            \"versionType\": \"maven\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"4.23.0\",\n                            \"versionType\": \"maven\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://camel.apache.org/security/CVE-2026-84180.html","https://issues.apache.org/jira/browse/CAMEL-24428","https://github.com/apache/camel/pull/25685","https://github.com/apache/camel/pull/25835","https://github.com/apache/camel/pull/25836"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-84180","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-84180","identifiers":["CVE-2026-84180"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
