xmldom: Processing Instruction Target Injection Bypasses requireWellFormed

Summary Document.createProcessingInstruction in @xmldom/xmldom performs no validation on the target parameter. The requireWellFormed: true serializer option validates only for : in the target and a case-insensitive xml prefix, but does not check for characters. A in the target breaks the processi...

GHSA-27P8-2357-5QQV xmldom: DocType `name` Injection Bypasses requireWellFormed

Summary The @xmldom/xmldom serializer emits DocumentType.name verbatim into the declaration with no well-formedness guard. GHSA-f6ww-3ggp-fr8h CVE-2026-41674 hardened the serializer's requireWellFormed path for a DocumentType's sibling fields — publicId, systemId, and internalSubset — but it did...

GHSA-W2RR-34G9-RVRJ xmldom: Element name injection via createElement() bypasses requireWellFormed

Summary Document.createElement in @xmldom/xmldom accepts arbitrary strings as the tagName parameter with zero validation. The serializer emits the tag name verbatim into XML/HTML output. Critically, the requireWellFormed: true serializer option — the recommended mitigation from CVE-2026-41672,...

GHSA-4W3W-2RP5-G8JM xmldom: Attribute name injection via setAttribute() bypasses requireWellFormed

Summary Element.setAttribute in @xmldom/xmldom bypasses attribute name validation by calling the private createAttributename method, which performs no validation. The public createAttribute method correctly validates names against an anchored QName pattern, but setAttribute never uses it. The...

CVE-2026-83618

xmldom is a pure JavaScript W3C DOMParser/XMLSerializer module. In versions 0.9.10 through 0.9.12 , the requireWellFormed: true serializer validates DocumentType.publicId and DocumentType.systemId using regexes (PubidLiteral_match, SystemLiteral_match) that inherit the multiline flag . A valid li...
