Title

Apache Camel: Camel-Vertx-Http: Unsafe Java deserialization of HTTP response bodies via a raw ObjectInputStream when transferException is enabled

Summary

Deserialization of Untrusted Data vulnerability in Apache Camel. The camel-vertx-http component deserializes HTTP response bodies carrying the Content-Type application/x-java-serialized-object using a raw java.io.ObjectInputStream, without applying any ObjectInputFilter (VertxHttpHelper.deserializeJavaObjectFromStream) This deserialization path is reached only when the producer endpoint is configured with transferException=true (or the component-level allowJavaSerializedObject=true) and throwExceptionOnFailure is left at its default value of true; in that case a backend HTTP response with a 5xx status and the application/x-java-serialized-object content type has its body deserialized with no class restrictions. An attacker who controls the backend the Camel producer talks to - through a man-in-the-middle position on an unencrypted (plain HTTP) connection, or by compromising the backend service - can return a crafted serialized Java object and, if a suitable gadget chain is present on the classpath, achieve remote code execution on the Camel application host. The path is not reachable in the default configuration, where transferException is false. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.20.0. Users are recommended to upgrade to version 4.20.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, the deserialization performed by both helper utilities is constrained by a default ObjectInputFilter (allow-list java.**;javax.**;org.apache.camel.**;!*), which can be customised through the new deserializationFilter endpoint option or the JVM-wide -Djdk.serialFilter system property. For deployments that cannot upgrade immediately: do not enable transferException=true (or allowJavaSerializedObject=true) on producers that talk to untrusted or network-reachable backends; ensure producer connections use TLS (https) so that a response cannot be substituted by a man-in-the-middle; and, where the option is required, set an explicit -Djdk.serialFilter allow-list (for example java.**;org.apache.camel.**;!*) to constrain deserialization.

            "value": "Vulnerabilidad de deserializaci\u00f3n de datos no confiables en Apache Camel.\n\nEl componente camel-vertx-http deserializa los cuerpos de respuesta HTTP que llevan el Content-Type application/x-java-serialized-object usando un java.io.ObjectInputStream sin procesar, sin aplicar ning\u00fan ObjectInputFilter (VertxHttpHelper.deserializeJavaObjectFromStream). Esta ruta de deserializaci\u00f3n se alcanza solo cuando el endpoint del productor est\u00e1 configurado con transferException=true (o el allowJavaSerializedObject=true a nivel de componente) y throwExceptionOnFailure se deja en su valor predeterminado de true; en ese caso, una respuesta HTTP del backend con un estado 5xx y el tipo de contenido application/x-java-serialized-object tiene su cuerpo deserializado sin restricciones de clase. Un atacante que controla el backend con el que se comunica el productor de Camel - a trav\u00e9s de una posici\u00f3n de man-in-the-middle en una conexi\u00f3n no cifrada (HTTP simple), o comprometiendo el servicio de backend - puede devolver un objeto Java serializado manipulado y, si una cadena de gadgets adecuada est\u00e1 presente en el classpath, lograr la ejecuci\u00f3n remota de c\u00f3digo en el host de la aplicaci\u00f3n Camel. La ruta no es alcanzable en la configuraci\u00f3n predeterminada, donde transferException es false.\nEste problema afecta a Apache Camel: desde 4.0.0 antes de 4.14.8, desde 4.15.0 antes de 4.18.3, desde 4.19.0 antes de 4.20.0.\n\nSe recomienda a los usuarios actualizar a la versi\u00f3n 4.20.0, que corrige el problema. Si los usuarios est\u00e1n en la rama de versiones LTS 4.14.x, se sugiere que actualicen a 4.14.8. Si los usuarios est\u00e1n en la rama de versiones 4.18.x, se sugiere que actualicen a 4.18.3. Despu\u00e9s de la actualizaci\u00f3n, la deserializaci\u00f3n realizada por ambas utilidades auxiliares est\u00e1 restringida por un ObjectInputFilter predeterminado (lista de permitidos java.;javax.;org.apache.camel.**;!*), que puede personalizarse a trav\u00e9s de la nueva opci\u00f3n de endpoint deserializationFilter o la propiedad del sistema -Djdk.serialFilter a nivel de JVM. Para implementaciones que no pueden actualizarse inmediatamente: no habilite transferException=true (o allowJavaSerializedObject=true) en productores que se comunican con backends no confiables o accesibles por red; aseg\u00farese de que las conexiones del productor usen TLS (HTTPS) para que una respuesta no pueda ser sustituida por un man-in-the-middle; y, donde la opci\u00f3n sea requerida, establezca una lista de permitidos -Djdk.serialFilter expl\u00edcita (por ejemplo, java.;org.apache.camel.;!*) para restringir la deserializaci\u00f3n."

Summary

Apache Camel-Vertx-Http and Camel-Netty-Http: Unsafe Java deserialization of HTTP response bodies via a raw ObjectInputStream when transferException is enabled

Details

Deserialization of Untrusted Data vulnerability in Apache Camel.

The camel-vertx-http component deserializes HTTP response bodies carrying the Content-Type application/x-java-serialized-object using a raw java.io.ObjectInputStream, without applying any ObjectInputFilter (VertxHttpHelper.deserializeJavaObjectFromStream) This deserialization path is reached only when the producer endpoint is configured with transferException=true (or the component-level allowJavaSerializedObject=true) and throwExceptionOnFailure is left at its default value of true; in that case a backend HTTP response with a 5xx status and the application/x-java-serialized-object content type has its body deserialized with no class restrictions. An attacker who controls the backend the Camel producer talks to - through a man-in-the-middle position on an unencrypted (plain HTTP) connection, or by compromising the backend service - can return a crafted serialized Java object and, if a suitable gadget chain is present on the classpath, achieve remote code execution on the Camel application host. The path is not reachable in the default configuration, where transferException is false. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.20.0.

Users are recommended to upgrade to version 4.20.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, the deserialization performed by both helper utilities is constrained by a default ObjectInputFilter (allow-list java.;javax.;org.apache.camel.**;!), which can be customised through the new deserializationFilter endpoint option or the JVM-wide -Djdk.serialFilter system property. For deployments that cannot upgrade immediately: do not enable transferException=true (or allowJavaSerializedObject=true) on producers that talk to untrusted or network-reachable backends; ensure producer connections use TLS (https) so that a response cannot be substituted by a man-in-the-middle; and, where the option is required, set an explicit -Djdk.serialFilter allow-list (for example java.;org.apache.camel.;!) to constrain deserialization.

CVE-2026-40859

A flaw was found in the `camel-vertx-http` component of Apache Camel. This vulnerability, a Deserialization of Untrusted Data, could allow a remote attacker to execute arbitrary code. By controlling the backend server or acting as a man-in-the-middle, an attacker could send a specially crafted serialized Java object. If the producer endpoint is configured to transfer exceptions, this could lead to remote code execution on the affected Camel application.
