Debezium is a distributed platform that turns your existing databases into event streams, so applications can see and respond immediately to each row-level change in the databases. Debezium is built on top of Apache Kafka and provides Kafka Connect compatible connectors that monitor specific database management systems. Debezium records the history of data changes in Kafka logs, from where your application consumes them. This makes it possible for your application to easily consume all of the events correctly and completely. Even if your application stops unexpectedly, it will not miss anything: when the application restarts, it will resume consuming the events where it left off. In addition this errata fixes two security issues mchange-commons-java: Arbitrary code execution via JNDI dereferencing of crafted objects (CVE-2026-27727) c3p0: Arbitrary Code Execution via deserialization of crafted objects (CVE-2026-27830)

Red Hat build of Apache Camel 4.14.4 for Spring Boot patch release and security update is now available. The purpose of this text-only errata is to inform you about the security issues fixed. Security Fix(es): * undertow-core: Undertow HTTP Server Fails to Reject Malformed Host Headers Leading to Potential Cache Poisoning and SSRF (CVE-2025-12543) * vertx-core: static handler component cache can be manipulated to deny the access to static files (CVE-2026-1002) * mchange-commons-java: mchange-commons-java: Arbitrary code execution via JNDI dereferencing of crafted objects (CVE-2026-27727) * com.mchange/c3p0: c3p0: Arbitrary Code Execution via deserialization of crafted objects (CVE-2026-27830)

mchange-commons-java, a library that provides Java utilities, includes code that mirrors early implementations of JNDI functionality, including support for remote `factoryClassLocation` values, by which code can be downloaded and invoked within a running application. If an attacker can provoke an application to read a maliciously crafted `jaxax.naming.Reference` or serialized object, they can provoke the download and execution of malicious code. Implementations of this functionality within the JDK were disabled by default behind a System property that defaults to `false`, `com.sun.jndi.ldap.object.trustURLCodebase`. However, since mchange-commons-java includes an independent implementation of JNDI derefencing, libraries (such as c3p0) that resolve references via that implementation could be provoked to download and execute malicious code even after the JDK was hardened. Mirroring the JDK patch, mchange-commons-java's JNDI functionality is gated by configuration parameters that default to restrictive values starting in version 0.4.0. No known workarounds are available. Versions prior to 0.4.0 should be avoided on application CLASSPATHs.
