The issue occurs because the parser uses a single internal variable to store both the remaining chunk size and state flags. By sending a specially crafted request with an extremely large chunk size, an attacker can cause these values to overlap, tricking the parser into thinking a request has finished prematurely. This can allow a second, \"smuggled\" request to be processed out of sync, potentially bypassing security controls."}],"affected":[{"vendor":"Red Hat","product":"Red Hat build of Apache Camel for
