CVE-2026-66713 is a critical-severity vulnerability affecting apache axis2\/java. It was published on July 28, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from apache. Update axis2\/java to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
