CVE-2026-41674— xmldom: XML injection through unvalidated DocumentType serialization

xmldom: XML injection through unvalidated DocumentType serialization

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 serializes DocumentType node fields (internalSubset, publicId, systemId) verbatim without any escaping or validation. When these fields are set programmatically to attacker-controlled strings, XMLSerializer.serializeToString can produce output where the DOCTYPE declaration is terminated early and arbitrary markup appears outside it. This issue has been patched in versions @xmldom/xmldom versions 0.9.10 and 0.8.13.

XMLDOM 安全漏洞

XMLDOM是jindw个人开发者的一个 W3C DOM for Node 的 JavaScript 实现。 XMLDOM 0.9.10之前版本、0.8.13之前版本和xmldom 0.6.0及之前版本存在安全漏洞，该漏洞源于序列化DocumentType节点字段时未进行转义或验证，可能导致DOCTYPE声明提前终止并注入任意标记。
