Secure XML processing for Python. Drop-in replacement for defusedxml.
Features
- Safe wrappers for all stdlib XML parsers (ElementTree, minidom, SAX, pulldom, expat)
- Blocks entity expansion bombs (Billion Laughs), XXE injection, DTD retrieval
- Configurable limits for entity expansions, DTD depth, element depth, XML size
- Zero runtime dependencies, Python 3.10+
- Full type annotations (PEP 561)
- defusedxml compatibility layer for zero-change migration
