Title

Apache Camel: Permissive default ObjectInputFilter pattern admits java.net.** and enables DNS-based information disclosure

Summary

Deserialization of Untrusted Data vulnerability in Apache Camel. The default ObjectInputFilter pattern shipped with several Apache Camel components for defense-in-depth deserialization filtering ('java.**;javax.**;org.apache.camel.**;!*', or the no-'javax.**' variant in the aggregation-repository components) uses a recursive 'java.**' glob that admits classes whose hashCode/equals/readObject methods perform network I/O, notably java.net.URL and java.net.InetAddress. When an attacker can deliver a Java-serialized payload to an affected Camel consumer, deserialization of a HashMap (or any collection that calls hashCode on its elements) containing java.net.URL keys causes the JVM to issue DNS queries to the attacker-supplied host during the deserialization side-effect. The class-level filter check passes because the resulting object's class (HashMap) is allow-listed; the DNS query is observable on an attacker-controlled DNS server, providing an out-of-band side channel. The exposure is highest on the camel-jms family because JmsBinding.extractBodyFromJms invokes ObjectMessage.getObject() unconditionally when mapJmsMessage=true (default). Affected components: camel-jms, camel-sjms, camel-amqp, camel-mina, camel-netty, camel-netty-http, camel-vertx-http, camel-infinispan, and the aggregation repository components camel-leveldb, camel-cassandraql, camel-consul, camel-sql (JDBC aggregation repository). This issue affects Apache Camel: from 4.14.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to a version that contains the CAMEL-23372 fix once available: 4.21.0 for the 4.21.x line, 4.18.3 for the 4.18.x line, and 4.14.8 for the 4.14.x line. For deployments that cannot upgrade immediately, configure a JMS-provider-side allow-list (Apache ActiveMQ Artemis 'deserializationAllowList' / 'deserializationDenyList', Apache ActiveMQ Classic 'org.apache.activemq.SERIALIZABLE_PACKAGES') as the primary mitigation, and/or override the in-code default via the endpoint-level 'deserializationFilter' option or the JVM-wide '-Djdk.serialFilter' system property with an explicit deny: '!java.net.**;java.**;javax.**;org.apache.camel.**;!*' (or '!java.net.**;java.**;org.apache.camel.**;!*' for the aggregation-repository components, which do not include javax.**).

Affected components: camel-jms, camel-sjms, camel-amqp, camel-mina, camel-netty, camel-netty-http, camel-vertx-http, camel-infinispan, and the aggregation repository components camel-leveldb, camel-cassandraql, camel-consul, camel-sql (JDBC aggregation repository).\nThis issue affects Apache Camel: from 4.14.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.\n\nUsers are recommended to upgrade to a version that contains the CAMEL-23372 fix once available: 4.21.0 for the 4.21.x line, 4.18.3 for the 4.18.x line, and 4.14.8 for the 4.14.x line. For deployments that cannot upgrade immediately, configure a JMS-provider-side allow-list (Apache ActiveMQ Artemis \u0027deserializationAllowList\u0027 / \u0027deserializationDenyList\u0027, Apache ActiveMQ Classic \u0027org.apache.activemq.SERIALIZABLE_PACKAGES\u0027) as the primary mitigation, and/or override the in-code default via the endpoint-level \u0027deserializationFilter\u0027 option or the JVM-wide \u0027-Djdk.serialFilter\u0027 system property with an explicit deny: \u0027!java.net.**;java.**;javax.**;org.apache.camel.**;!*\u0027 (or \u0027!java.net.**;java.**;org.apache.camel.**;!*\u0027 for the aggregation-repository components, which do not include javax.**)."

Cuando un atacante puede entregar una carga \u00fatil serializada en Java a un consumidor de Camel afectado, la deserializaci\u00f3n de un HashMap (o cualquier colecci\u00f3n que llame a hashCode en sus elementos) que contiene claves java.net.URL hace que la JVM emita consultas DNS al host proporcionado por el atacante durante el efecto secundario de la deserializaci\u00f3n. La verificaci\u00f3n del filtro a nivel de clase pasa porque la clase del objeto resultante (HashMap) est\u00e1 en la lista de permitidos; la consulta DNS es observable en un servidor DNS controlado por el atacante, proporcionando un canal lateral fuera de banda.

When an attacker can deliver a Java-serialized payload to an affected Camel consumer, deserialization of a HashMap (or any collection that calls hashCode on its elements) containing java.net.URL keys causes the JVM to issue DNS queries to the attacker-supplied host during the deserialization side-effect. The class-level filter check passes because the resulting object\u0027s class (HashMap) is allow-listed; the DNS query is observable on an attacker-controlled DNS server, providing an out-of-band side channel. The exposure is highest on the camel-jms family because JmsBinding.extractBodyFromJms invokes ObjectMessage.getObject() unconditionally when mapJmsMessage=true (default).

Summary

Apache Camel: Permissive default ObjectInputFilter pattern admits java.net.** and enables DNS-based information disclosure

Details

Deserialization of Untrusted Data vulnerability in Apache Camel.

The default ObjectInputFilter pattern shipped with several Apache Camel components for defense-in-depth deserialization filtering ('java.;javax.;org.apache.camel.**;!*', or the no-'javax.' variant in the aggregation-repository components) uses a recursive 'java.' glob that admits classes whose hashCode/equals/readObject methods perform network I/O, notably java.net.URL and java.net.InetAddress. When an attacker can deliver a Java-serialized payload to an affected Camel consumer, deserialization of a HashMap (or any collection that calls hashCode on its elements) containing java.net.URL keys causes the JVM to issue DNS queries to the attacker-supplied host during the deserialization side-effect. The class-level filter check passes because the resulting object's class (HashMap) is allow-listed; the DNS query is observable on an attacker-controlled DNS server, providing an out-of-band side channel. The exposure is highest on the camel-jms family because JmsBinding.extractBodyFromJms invokes ObjectMessage.getObject() unconditionally when mapJmsMessage=true (default). Affected components: camel-jms, camel-sjms, camel-amqp, camel-mina, camel-netty, camel-netty-http, camel-vertx-http, camel-infinispan, and the aggregation repository components camel-leveldb, camel-cassandraql, camel-consul, camel-sql (JDBC aggregation repository). This issue affects Apache Camel: from 4.14.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.

Users are recommended to upgrade to a version that contains the CAMEL-23372 fix once available: 4.21.0 for the 4.21.x line, 4.18.3 for the 4.18.x line, and 4.14.8 for the 4.14.x line. For deployments that cannot upgrade immediately, configure a JMS-provider-side allow-list (Apache ActiveMQ Artemis 'deserializationAllowList' / 'deserializationDenyList', Apache ActiveMQ Classic 'org.apache.activemq.SERIALIZABLE_PACKAGES') as the primary mitigation, and/or override the in-code default via the endpoint-level 'deserializationFilter' option or the JVM-wide '-Djdk.serialFilter' system property with an explicit deny: '!java.net.;java.;javax.;org.apache.camel.;!*' (or '!java.net.;java.;org.apache.camel.**;!*' for the aggregation-repository components, which do not include javax.**).

When an attacker can deliver a Java-serialized payload to an affected Camel consumer, deserialization of a HashMap (or any collection that calls hashCode on its elements) containing java.net.URL keys causes the JVM to issue DNS queries to the attacker-supplied host during the deserialization side-effect. The class-level filter check passes because the resulting object\u0027s class (HashMap) is allow-listed; the DNS query is observable on an attacker-controlled DNS server, providing an out-of-band side channel. The exposure is highest on the camel-jms family because JmsBinding.extractBodyFromJms invokes ObjectMessage.getObject() unconditionally when mapJmsMessage=true (default). Affected components: camel-jms, camel-sjms, camel-amqp, camel-mina, camel-netty, camel-netty-http, camel-vertx-http, camel-infinispan, and the aggregation repository components camel-leveldb, camel-cassandraql, camel-consul, camel-sql (JDBC aggregation repository).\nThis issue affects Apache Camel: from 4.14.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.\n\nUsers are recommended to upgrade to a version that contains the CAMEL-23372 fix once available: 4.21.0 for the 4.21.x line, 4.18.3 for the 4.18.x line, and 4.14.8 for the 4.14.x line. For deployments that cannot upgrade immediately, configure a JMS-provider-side allow-list (Apache ActiveMQ Artemis \u0027deserializationAllowList\u0027 / \u0027deserializationDenyList\u0027, Apache ActiveMQ Classic \u0027org.apache.activemq.SERIALIZABLE_PACKAGES\u0027) as the primary mitigation, and/or override the in-code default via the endpoint-level \u0027deserializationFilter\u0027 option or the JVM-wide \u0027-Djdk.serialFilter\u0027 system property with an explicit deny: \u0027!java.net.**;java.**;javax.**;org.apache.camel.**;!*\u0027 (or \u0027!java.net.**;java.**;org.apache.camel.**;!*\u0027 for the aggregation-repository components, which do not include javax.**).",

CVE-2026-42527

A flaw was found in Apache Camel. This deserialization of untrusted data vulnerability allows a remote attacker to trigger out-of-band DNS queries to an attacker-controlled host. By sending a specially crafted Java-serialized payload to an affected Camel consumer, the system's Java Virtual Machine (JVM) can be coerced into performing DNS lookups during the deserialization process. This provides an attacker with an information disclosure side channel, with the highest risk observed in the camel-jms family of components.
