Summary
OWSLib vulnerable to XML External Entity (XXE) Injection
Details

Impact

OWSLib's XML parser (which supports both lxml and xml.etree) does not disable entity resolution for lxml, and could lead to arbitrary file reads from an attacker-controlled XML payload. This affects all XML parsing in the codebase.

Patches

  • Use only lxml for XML handling, adding resolve_entities=False to lxml's parser: https://github.com/geopython/OWSLib/pull/863

Workarounds

patch_well_known_namespaces(etree)
etree.set_default_parser(
    parser=etree.XMLParser(resolve_entities=False)
)
