CVE-2026-85312Network attack vectorHinoki check available

Saga hijacking via unfiltered coordinator header

Published Oct 19, 2026 · Updated Oct 19, 2026

Header injection in Apache Camel Core allows remote attackers to hijack saga participation through inbound message headers. SagaProcessor.getCurrentSagaCoordinator() trusts the unfiltered Long-Running-Action header to select another action, misassociating requests or compensation. Exposure requires an inbound path into a saga route; although the advisory limits exposure to LRA coordinators, upstream patch documentation explicitly identifies non-LRA services as affected.
