What to do
Solution (from the CVE record)
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, puts a generic description in the status instead of the route exception's message. Set muteException=false to restore the previous output.
Workaround (from the CVE record)
For deployments that cannot upgrade immediately, map failures onto an explicit status in an onException handler so the framework never copies the exception message into the description.
Advisories and patches
- Fix on main, released in 4.23.0 (commit 3c99874122e0c4dbad655a1e32bbcaf48cee1e67)
- Backport to camel-4.22.x, released in 4.22.1 (commit 9a6e8222085ed12f73ce76f826aeb69e9d111ff8)
- Backport to camel-4.18.x, released in 4.18.5 (commit e6986906e41b3e537d3a5d278525bc09b78b4127)

Description
Apache Camel: Camel-gRPC Information Disclosure via Unmuted Consumer Exceptions
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel gRPC component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When a route behind a gRPC consumer failed, the exception's message was placed into the gRPC status description. Unlike the status cause, which stays local to the server, the description is transmitted to the calling client, so an external caller able to provoke a failure could read the internal error message. What that discloses depends on the exception, and in practice includes class and package names, paths, host names and connection detail carried in messages. This is the gRPC member of the same unmuted-consumer-exception family as the knative, mina and CXF advisories published alongside it. 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, puts a generic description in the status instead of the route exception's message. Set muteException=false to restore the previous output. For deployments that cannot upgrade immediately, map failures onto an explicit status in an onException handler so the framework never copies the exception message into the description.
