Prior to @xmldom/xmldom versions 0.8.15 and 0.9.12, and in xmldom version 0.6.0 and earlier, Document.createEntityReference(name) accepts an invalid name and the ENTITY_REFERENCE_NODE serializer emits the resulting nodeName directly in &name; form. Directly serializing the node or fragment with XMLSerializer.serializeToString() and requireWellFormed: true can therefore break the entity-reference boundary and produce attacker-controlled XML markup when reparsed. The parser does not ordinarily create these nodes, and element-child insertion is rejected, so exploitation requires an application to create and directly serialize an EntityReference. This issue is fixed in @xmldom/xmldom versions 0.8.15 and 0.9.12; no fixed version is available for xmldom.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-83610)\n\nAffected packages:\n\n- `@xmldom/xmldom >= 0.7.0, <= 0.8.14`\n- `@xmldom/xmldom >= 0.9.0, <= 0.9.11`\n- `xmldom <= 0.6.0`\n\nPatched in:\n\n- `@xmldom/xmldom 0.8.15`\n- `@xmldom/xmldom 0.9.12`\n\nSource: https://github.com/advisories/GHSA-6gmq-8vp8-gcm6\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Build of Podman Desktop, Red Hat Developer Hub, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat Fuse 7, … · no fix planned: Red Hat Fuse 7, Red Hat Build of Podman Desktop, Red Hat Developer Hub, Red Hat Enterprise Linux 10, … · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-83610.json)","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":208937,"id":"CVE-2026-83610","ts":1790062295696,"field":"cvss","old":null,"new":"5.3"}]}
