CVE-2026-66713

Deserialization of Untrusted Data (CWE-502) in the Tribes-based clustering component in Apache Software Foundation Apache Axis2/Java through 2.0.0 on Apache Tomcat (only when Tribes clustering is enabled, which is off by default) allows an unauthenticated remote attacker with network access to the clustering port to execute arbitrary code via a crafted serialized Java object delivered to the cluster channel and deserialized in org.apache.axis2.clustering.tribes.Axis2ChannelListener#messageReceived. Users are recommended to upgrade to version 2.0.1, which fixes this issue by removing the clustering feature entirely.

Summary		(es) Deserialización de datos no confiables (CWE-502) en el componente de clustering basado en Tribes en Apache Software Foundation Apache Axis2/Java hasta 2.0.0 en Apache Tomcat (solo cuando el clustering de Tribes está habilitado, que está desactivado por defecto) permite a un atacante remoto no autenticado con acceso de red al puerto de clustering ejecutar código arbitrario a través de un objeto Java serializado manipulado entregado al canal del cluster y deserializado en org.apache.axis2.clustering.tribes.Axis2ChannelListener#messageReceived. Se recomienda a los usuarios actualizar a la versión 2.0.1, que soluciona este problema al eliminar la característica de clustering por completo.
