Security Bulletin: IBM WebSphere Application Server Liberty is affected by an XML External Entity Injection vulnerability due to Apache CXF (CVE-2026-65432)

Summary There is a vulnerability in the Apache CXF library that affects IBM WebSphere Application Server Liberty with jaxws-2.2, xmlWS-3.0, xmlWS-4.0, wsSecurity-1.1 or wsAtomicTransaction-1.2 enabled. Vulnerability Details CVEID:CVE-2026-65432 DESCRIPTION: Apache CXF reads a top-level WSDL throu...

XML External Entity (XXE) Injection

Overview Affected versions of this package are vulnerable to XML External Entity XXE Injection in the WSDL/XSD import process. An attacker can access sensitive files or internal resources by supplying crafted XML documents containing external entity references, which are processed when imported...

CVE-2026-65432

The Apache CXF library is vulnerable to XML External Entity (XXE) attacks because it fails to extend protections to imported content. While Apache CXF uses a hardened StaxUtils path to disable DTDs and external entities for top-level WSDLs, any or references are passed to WSDL4J . Unlike CXF, W...

CVE-2026-65432 Apache CXF: XXE via WSDL/XSD import parsing

Apache CXF reads a top-level WSDL through its hardened StaxUtils path, which disables XML DTDs and external entities. However, any or 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...

UBUNTU-CVE-2026-58501

Zeep is a Python SOAP client. From 4.0.0 before 4.3.3, Settings.forbidexternal is defined but not enforced when parsing WSDL or XSD documents, allowing transitive xsd:import, xsd:include, wsdl:import, and lxml entity or DTD references to fetch attacker-chosen HTTP or HTTPS URLs. This issue is fix...

EUVD-2026-39577

A flaw was found in Apicurio Registry. The WSDLReaderAccessor creates a wsdl4j WSDLReader without disabling the javax.wsdl.importDocuments feature. When the VALIDITY rule is set to FULL, an attacker with Developer-role access can upload a WSDL document containing attacker-controlled import...

CVE-2026-12992

Apicurio Registry is affected by an SSRF flaw in the WSDL handling path. The WSDLReaderAccessor constructs a wsdl4j WSDLReader without disabling javax.wsdl.importDocuments, and with the FULL VALIDITY rule enabled, a Developer-role user can upload a WSDL with attacker-controlled import locations, ...

CVE-2026-12992 Apicurio/apicurio-registry: apicurio-registry: ssrf via wsdl4j import dereference in wsdl full validation

A flaw was found in Apicurio Registry. The WSDLReaderAccessor creates a wsdl4j WSDLReader without disabling the javax.wsdl.importDocuments feature. When the VALIDITY rule is set to FULL, an attacker with Developer-role access can upload a WSDL document containing attacker-controlled import...

GHSA-4CC2-G9W2-FHF6 Zeep: Server-Side Request Forgery (SSRF)

Summary When parsing a WSDL or XSD document, python-zeep follows transitive references — xsd:import, xsd:include, wsdl:import, and lxml entity/DTD resolution — and will fetch http/https URLs found in those references. The Settings.forbidexternal option, intended to disable this transitive remote...

CVE-2018-20580

The CVE-2018-20580 vulnerability affects SmartBear ReadyAPI 2.5.0 and 2.6.0, where WSDL import functionality can be abused to execute arbitrary Java code via a crafted parameter in a WSDL file. This is supported by multiple public references and exploits describing remote code execution. CVSSv3 b...

CVE-2018-20580: Improper Input Validation

The WSDL import functionality in SmartBear ReadyAPI 2.5.0 and 2.6.0 allows remote attackers to execute arbitrary Java code via a crafted request parameter in a WSDL file...
