xmldom: Denial of service via uncontrolled recursion in XML serialization
CVE-2026-41673 is fixed in node-xmldom on 1 platform by DEBIAN-CVE-2026-41673 (version 0.9.10-1), released May 7, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
