xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) `DOMParser` and `XMLSerializer` module. In @xmldom/xmldom prior to versions 0.9.10 and 0.8.13 and xmldom version 0.6.0 and prior, the package allows attacker-controlled processing instruction data to be serialized into XML without validating or neutralizing the PI-closing sequence ?>. As a result, an attacker can terminate the processing instruction early and inject arbitrary XML nodes into the serialized output. This issue has been patched in versions @xmldom/xmldom versions 0.9.10 and 0.8.13.

CVE-2026-41675 [HIGH] CWE-91 xmldom has XML node injection through unvalidated processing instruction serialization
xmldom has XML node injection through unvalidated processing instruction serialization
## Summary
The package allows attacker-controlled processing instruction data to be serialized into XML without validating or neutralizing the PI-closing sequence `?>`. As a result, an attacker can terminate the processing instruction early and inject arbitrary XML nodes into the serialized output.
---
## Details
The issue is in the DOM construction and serialization flow for processing instruction nodes.
When `createProcessingInstruction(target, data)` is called, the supplied `data` string is stored directly on the node without validation. Later, when the document is serialized, the serializer writes PI nodes by concatenating `` directly.
That behavior is unsafe because processing instructions ar

## Windows Netlogon: critical RCE
Anyone responsible for securing a domain controller should prioritize remediation of CVE-2026-41089 , which is a critical stack-based buffer overflow in Windows Netlogon with a CVSS v3 base score of 9.8. Exploitation leads to execution in the context of the Netlogon service, so that’s SYSTEM privileges on the domain controller. For most pentesters, that’s the point at which the customer report more or less writes itself. No privileges
