Title

Apache Camel: Camel-Mina Information Disclosure via Unmuted Consumer Exceptions

Summary

Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Mina 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, the Mina consumer wrote exchange.getException() straight back over the socket to the remote peer. Over a textline codec that hands the peer the exception's class name and message; over the object codec it hands over the serialised exception, cause chain included. A remote peer able to provoke a failure could therefore read internal detail about the deployment - class and package names, and whatever a message or nested cause happens to carry, which in practice can include paths, host names and connection detail. The consumer had no option to suppress this, unlike the HTTP-family consumers aligned 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. A muteException consumer option, defaulting to true, replaces the route exception with a generic one carrying no class name, message or stack trace, while still writing a reply so that a synchronous peer is not left to time out. Set muteException=false to restore the previous behaviour. For deployments that cannot upgrade immediately, add an onException handler that sets the reply body explicitly, so the framework never writes the exception back to the peer.

Vulnerability from github – Published: 2026-10-19 12:32 – Updated: 2026-10-19 12:32

Details

Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Mina 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, the Mina consumer wrote exchange.getException() straight back over the socket to the remote peer. Over a textline codec that hands the peer the exception's class name and message; over the object codec it hands over the serialised exception, cause chain included. A remote peer able to provoke a failure could therefore read internal detail about the deployment - class and package names, and whatever a message or nested cause happens to carry, which in practice can include paths, host names and connection detail. The consumer had no option to suppress this, unlike the HTTP-family consumers aligned 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. A muteException consumer option, defaulting to true, replaces the route exception with a generic one carrying no class name, message or stack trace, while still writing a reply so that a synchronous peer is not left to time out. Set muteException=false to restore the previous behaviour. For deployments that cannot upgrade immediately, add an onException handler that sets the reply body explicitly, so the framework never writes the exception back to the peer.
