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).\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 '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.**)."}], "lastModified": "2026-07-07T23:42:40.463", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:camel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "58BD2573-EEBB-4D76-B3B7-038A53515204", "versionEndExcluding": "4.14.8", "versionStartIncluding": "4.14.0"}, {"criteria": "cpe:2.3:a:apache:camel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3F672322-AA52-4621-B687-76B5AC9D619F", "versionEndExcluding": "4.18.3", "versionStartIncluding": "4.18.0"}, {"criteria": "cpe:2.3:a:apache:camel:4.20.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "526A7504-CAAA-43DD-97B2-8A18093E97C9"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
