NewCVE-2026-49098 (opens in a new tab)How to fix?
Upgrade org.apache.camel:camel-kafka to version 4.14.8, 4.18.3, 4.21.0 or higher.
Overview
Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes via the kafka.OVERRIDE_TOPIC and other kafka.* headers that bypass the upstream HTTP header filter. An attacker can redirect messages to arbitrary Kafka topics or inject crafted messages into sensitive topics by supplying specially crafted HTTP headers. This is only exploitable if an HTTP consumer is bridged to a Kafka producer and the HTTP endpoint is unauthenticated.
Workaround
This vulnerability can be mitigated by stripping kafka.* headers from any untrusted ingress before the Kafka producer, for example by using removeHeaders('kafka.*') at the start of the route, and ensuring the target topic is set from a trusted source.
