Doc Text:
A flaw was found in the `xmldom` library, a JavaScript module for parsing XML documents. An attacker could exploit this vulnerability by providing a specially crafted, deeply nested XML document. This could lead to a Denial of Service (DoS) by causing the application to crash due to excessive recursion.

Description OSIDB Bzimport 2026-05-07 05:02:25 UTC
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.
