A fix was pushed into the master branch but not yet published.
Overview
Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity in the xml.dom.minidom methods like appendChild() due to the dependancy on the _clear_id_cache() algorithm when processing excessively nested XML documents. An attacker can exhaust system resources and impact application availability by submitting deeply nested XML structures.
