The vulnerability stems from improper XML parsing configuration. The release notes for 1.2.1 explicitly mention switching to defusedxml to prevent XXE attacks, indicating the core parsing function (untangle.parse) was previously using an insecure XML parser. This aligns with standard XXE vulnerability patterns where failure to configure safe parsing options (like disabling external entities) in XML processing functions creates exposure.
