GHSA-965W-775F-MR7G xmldom: Quadratic-memory consumption

Summary When an element declares a namespace prefix, xmldom copies the entire in-scope namespace map into a fresh object and keeps that copy on the element while it is open on the parse stack. A crafted document that nests N elements, each declaring one unique prefix, therefore drives the parser ...
