CVE-2026-65432— Apache CXF: XXE via WSDL/XSD import parsing
Quick assessment
Affected
Apache Software Foundation Apache CXF
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache CXF 通过其加固的 StaxUtils 路径解析顶层 WSDL 文件，该路径已禁用 XML DTD 和外部实体。然而，从该顶层 WSDL 引用的任何 或 元素会被交由 WSDL4J 处理，而 WSDL4J 并未禁用 DOCTYPE 声明或外部实体。因此，应用于顶层文档的安全防护措施并未延伸至被导入的文档，导致导入的 WSDL/XSD 内容易受 XML 外部实体（XXE）攻击。建议用户升级至修复了此问题的版本 4.2.3、4.1.8 或 3.6.12。

Vulnerability Title
Apache CXF: XXE via WSDL/XSD import parsing
Source: CVE Program / CVE List V5
Vulnerability 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.
