CVE-2026-65432: Apache Cxf

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

Apache CXF reads a top-level WSDL through its hardened StaxUtils path, which disables XML DTDs and external entities. However, any <wsdl:import> or <xsd:import> referenced from that top-level WSDL is handed off to WSDL4J, which does not disable DOCTYPE declarations or external entities. As a result, the protections applied to the top-level document do not extend to imported documents, leaving imported WSDL/XSD content vulnerable to XML External Entity (XXE) attacks. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.

Affected products

• Apache Cxf: before 3.6.12 (fixed in 3.6.12); from 4.0.0, before 4.1.8 (fixed in 4.1.8); from 4.2.0, before 4.2.3 (fixed in 4.2.3)
