What is CVE-2026-41675?

The xmldom module, which implements the W3C standard for XML DOM, contains a vulnerability that permits the serialization of attacker-controlled processing instruction data. This flaw can allow an attacker to manipulate the XML output by prematurely terminating processing instructions, potentially leading to the injection of arbitrary XML nodes. Affected users should upgrade to versions @xmldom/xmldom 0.9.10, 0.8.13 or xmldom 0.6.0 and above to mitigate this risk.

Affected Version(s)

xmldom xmldom <= 0.6.0 <= xmldom 0.6.0

xmldom @xmldom/xmldom >= 0.9.0, < 0.9.10 < @xmldom/xmldom 0.9.0, 0.9.10

xmldom @xmldom/xmldom < 0.8.13 < @xmldom/xmldom 0.8.13
