CVE-2026-41673 PUBLISHED

xmldom: Denial of service via uncontrolled recursion in XML serialization

Assigner: GitHub_M
Reserved: 22.04.2026 Published: 07.05.2026 Updated: 07.05.2026

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, seven recursive traversals in lib/dom.js operate without a depth limit. A sufficiently deeply nested DOM tree causes a RangeError: Maximum call stack size exceeded, crashing the application. This issue has been patched in versions @xmldom/xmldom versions 0.9.10 and 0.8.13.
