    Misinterpretation of malicious XML input

    xmldom

    Overview

    Impact

    xmldom versions 0.4.0 and older do not correctly preserve system identifiers, FPIs or namespaces when repeatedly parsing and serializing maliciously crafted documents.

    This may lead to unexpected syntactic changes during XML processing in some downstream applications.

    Workarounds

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

    Remediation

    Update to 0.5.0 or later
