CVE-2026-83615

A flaw was found in xmldom, a JavaScript library for parsing XML documents. A remote attacker could exploit this vulnerability by providing a specially crafted XML document. When processed, this document would cause the library to consume an excessive amount of memory, leading to the application running out of resources and becoming unavailable, a condition known as Denial of Service (DoS).

This is an Important denial of service vulnerability in the xmldom library, affecting Red Hat products that process untrusted XML input. Exploitation involves providing a crafted XML document with deeply nested elements and new namespace prefixes, which can lead to quadratic memory consumption and exhaust the process heap, causing service disruption.
