NewCVE-2026-56139 (opens in a new tab)How to fix?
Upgrade org.apache.camel:camel-undertow to version 4.14.8, 4.18.3, 4.21.0 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure in the muteException option handling of the HTTP consumer. An attacker can obtain sensitive internal information, such as Java stack traces containing credentials, hostnames, IP addresses, filesystem paths, and application structure, by sending malformed requests or triggering route-internal failures. This is only exploitable if the muteException option is set to false (the default), or for Rest DSL consumers where the option is ignored regardless of configuration.
Workaround
This vulnerability can be mitigated by explicitly setting muteException=true on the consumer or globally via the camel.component.undertow.mute-exception=true property; however, this does not mitigate the issue for Rest DSL consumers.
