CVE-2026-65432 Details
Description
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.
A vulnerability in Apache CXF allows for XML External Entity (XXE) attacks through improper handling of imported WSDL or XSD documents. While top-level WSDL files are processed with security measures that disable DTDs and external entities, any references to additional WSDL or XSD imports are managed by WSDL4J, which does not enforce these protections. This oversight leaves the imported content exposed to XXE vulnerabilities. The issue affects Apache CXF versions 4.2.0 prior to 4.2.3, 4.0.0 prior to 4.1.8, and versions prior to 3.6.12.
Users are advised to upgrade to Apache CXF versions 4.2.3, 4.1.8, or 3.6.12.
