Summary
Misinterpretation of malicious XML input
Details

Impact

xmldom versions 0.6.0 and older do not correctly escape special characters when serializing elements removed from their ancestor. This may lead to unexpected syntactic changes during XML processing in some downstream applications.

Patches

Update to one of the fixed versions of @xmldom/xmldom (>=0.7.0)

See issue #271 for the status of publishing xmldom to npm or join #270 for Q&A/discussion until it's resolved.

Workarounds

Downstream applications can validate the input and reject the maliciously crafted documents.
