Title
xmldom: XML injection through unvalidated DocumentType serialization
Summary
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.

This vulnerability allows an attacker to inject arbitrary XML markup into a document due to improper handling of DocumentType node fields during serialization. By crafting malicious input, an attacker can cause the XML serializer to prematurely terminate the DOCTYPE declaration, enabling the insertion of unauthorized content. This could lead to information disclosure or, in certain configurations, the execution of arbitrary code.\"}], \"problemTypes\": [{\"descriptions\": [{\"lang\": \"en\", \"type\": \"CWE\", \"cweId\": \"CWE-91\", \"description\": \"XML Injection (aka Blind XPath Injection)\"}]}], \"providerMetadata\": {\"orgId\": \"0b0ca135-0b70-47e7-9f44-1890c2a1c46c\", \"shortName\": \"redhat-SADP\", \"dateUpdated\": \"2026-07-27T12:05:29.726Z\"}}, {\"title\": \"CISA ADP Vulnrichment\", \"metrics\": [{\"other\": {\"type\": \"ssvc\", \"content\": {\"id\": \"CVE-2026-41674\", \"role\": \"CISA Coordinator\", \"options\": [{\"Exploitation\": \"poc\"}, {\"Automatable\": \"yes\"}, {\"Technical Impact\": \"partial\"}], \"version\": \"2.0.3\", \"timestamp\": \"2026-05-07T12:35:22.818916Z\"}}}], \"references\": [{\"url\": \"https://github.com/xmldom/xmldom/security/advisories/GHSA-f6ww-3ggp-fr8h\", \"tags\": [\"exploit\"]}], \"providerMetadata\": {\"orgId\": \"134c704f-9b21-4f2e-91b3-4a467353bcc0\", \"shortName\": \"CISA-ADP\", \"dateUpdated\": \"2026-05-07T12:35:12.270Z\"}}], \"cna\": {\"title\": \"xmldom: XML injection through unvalidated DocumentType serialization\", \"source\": {\"advisory\": \"GHSA-f6ww-3ggp-fr8h\", \"discovery\": \"UNKNOWN\"}, \"metrics\": [{\"cvssV4_0\": {\"version\": \"4.0\", \"baseScore\": 8.7, \"attackVector\": \"NETWORK\", \"baseSeverity\": \"HIGH\", \"vectorString\": \"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N\", \"userInteraction\": \"NONE\", \"attackComplexity\": \"LOW\", \"attackRequirements\": \"NONE\", \"privilegesRequired\": \"NONE\", \"subIntegrityImpact\": \"NONE\", \"vulnIntegrityImpact\": \"HIGH\", \"subAvailabilityImpact\": \"NONE\", \"vulnAvailabilityImpact\": \"NONE\", \"subConfidentialityImpact\": \"NONE\", \"vulnConfidentialityImpact\": \"NONE\"}}], \"affected\": [{\"vendor\": \"xmldom\", \"product\": \"xmldom\", \"versions\": [{\"status\": \"affected\", \"version\": \"xmldom \u003c= 0.6.0\"}, {\"status\": \"affected\", \"version\": \"@xmldom/xmldom \u003e= 0.9.0, \u003c 0.9.10\"}, {\"status\": \"affected\", \"version\": \"@xmldom/xmldom \u003c 0.8.13\"}]}], \"references\": [{\"url\": \"https://github.com/xmldom/xmldom/security/advisories/GHSA-f6ww-3ggp-fr8h\", \"name\": \"https://github.com/xmldom/xmldom/security/advisories/GHSA-f6ww-3ggp-fr8h\", \"tags\": [\"x_refsource_CONFIRM\"]}, {\"url\": \"https://github.com/xmldom/xmldom/commit/372008f9ae0e20fd69f761c7b79e202598267314\", \"name\": \"https://github.com/xmldom/xmldom/commit/372008f9ae0e20fd69f761c7b79e202598267314\", \"tags\": [\"x_refsource_MISC\"]}, {\"url\": \"https://github.com/xmldom/xmldom/releases/tag/0.8.13\", \"name\": \"https://github.com/xmldom/xmldom/releases/tag/0.8.13\", \"tags\": [\"x_refsource_MISC\"]}, {\"url\": \"https://github.com/xmldom/xmldom/releases/tag/0.9.10\", \"name\": \"https://github.com/xmldom/xmldom/releases/tag/0.9.10\", \"tags\": [\"x_refsource_MISC\"]}], \"descriptions\": [{\"lang\": \"en\", \"value\": \"xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) `DOMParser` and `XMLSerializer` module.
