Description OSIDB Bzimport 2026-06-12 10:01:46 UTC 
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, which fix this issue.
