Paul King updated GROOVY-11979:
-------------------------------
Description:
h3. Part 1 — FactorySupport hardened factories (secure by default)
*What's included:*
* {{FactorySupport.java}}: every factory method now returns a hardened factory
by default
** {{createDocumentBuilderFactory()}} — delegates to
{{createDocumentBuilderFactory(false)}}; previously returned a bare JDK factory
** {{createSaxParserFactory()}} — delegates to
{{createSaxParserFactory(false)}}; previously returned a bare JDK factory
** {{createDocumentBuilderFactory(boolean allowDocTypeDeclaration)}} *(new)*
** {{createSaxParserFactory(boolean allowDocTypeDeclaration)}} *(new)*
** {{createXMLInputFactory()}} *(new)*
** {{createXMLInputFactory(boolean allowDocTypeDeclaration)}} *(new)*
** {{createTransformerFactory(boolean allowDocTypeDeclaration, boolean
allowExternalResources)}} *(new)*
** {{createSchemaFactory(String schemaLanguage)}} *(new)*
** {{createXPathFactory()}} *(new)*
* {{FactorySupport.java}}: added private quiet helpers for the new factory
types (SchemaFactory, XPathFactory, TransformerFactory {{setAttribute}},
XMLInputFactory {{setProperty}}).
* {{FactorySupportTest.java}}: 14 new tests covering hardening defaults on both
the zero-arg and boolean overloads, relax-flag round-trips for each factory
type.
*Hardening recipes applied:*
|| Factory || Settings ||
| DocumentBuilderFactory | {{FEATURE_SECURE_PROCESSING=true}},
{{disallow-doctype-decl=!allow}}, {{XIncludeAware=false}},
{{ExpandEntityReferences=false}} |
| SAXParserFactory | {{FEATURE_SECURE_PROCESSING=true}},
{{disallow-doctype-decl=!allow}} |
| XMLInputFactory | {{SUPPORT_DTD=allow}},
{{IS_SUPPORTING_EXTERNAL_ENTITIES=false}} |
| TransformerFactory | {{FEATURE_SECURE_PROCESSING=true}},
{{disallow-doctype-decl=!allow}}, {{ACCESS_EXTERNAL_DTD}} and
{{ACCESS_EXTERNAL_STYLESHEET}} = {{"all"}} or {{""}} per
{{allowExternalResources}} |
| SchemaFactory | {{FEATURE_SECURE_PROCESSING=true}} (no {{ACCESS_EXTERNAL_*}}
— preserves legitimate {{<xs:import>}}) |
| XPathFactory | {{FEATURE_SECURE_PROCESSING=true}} |
*Compat notes:*
* Direct callers of the zero-arg {{createDocumentBuilderFactory()}} /
{{createSaxParserFactory()}} now receive hardened factories. Callers that
previously parsed DOCTYPE-bearing input through those factories must switch to
the {{(true)}} overload. Internal Groovy callers ({{XmlParser}},
{{XmlSlurper}}, {{XmlUtil}}, {{DOMBuilder}}) overlay their own settings on top
of the default and are unaffected.
* No public method signatures changed. No methods deprecated.
