Red Hat has released an official update (RHBQ 3.15.3.SP2) that addresses this vulnerability. Users should back up their existing installations, including applications and configurations, before applying the update. Additionally, as a mitigation, users can remove headers from their Camel routes either globally or on a per-route basis to reduce exposure. Applying the official update is the recommended remediation.
Description
CVE-2025-27636 is a moderate severity vulnerability in Apache Camel that allows bypassing header filters via a specially crafted HTTP response. This flaw arises from improper filtering of headers starting with "Camel" or "camel.", which can be exploited under specific configurations involving the camel-bean component as a producer and HTTP-based consumers. Exploitation could allow attackers to invoke certain methods on Java beans present in the classpath but does not permit arbitrary code execution or full system takeover. Red Hat has released an update (RHBQ 3.15.3.SP2) to address this issue in their build of Apache Camel 4.8 for Quarkus 3.15. Users are advised to back up their installations before applying the update.
