CVE-2026-85315
MEDIUM 5.3Generation 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.
