Apache CXF: XML External Entity (XXE) Injection in W3CMultiSchemaFactory and EndpointReferenceUtils

Published Jun 12, 2026 · Updated Aug 7, 2026 · Assigned by apache

Vendor: Apache Software Foundation Product: Apache CXF Package: org.apache.cxf:cxf-core Ecosystem: Maven

Description

Apache CXF's EndpointReferenceUtils and W3CMultiSchemaFactory classes construct a SAXParserFactory without the necessary JAXP hardening configurations, enabling out-of-band (OOB)
external entity resolution. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue.
