Description

A flaw was found in xmldom, a JavaScript XML DOM parser. The DOMParser.parseFromString() function can silently accept malformed XML end tags that include a line break and additional content. This unexpected parsing behavior causes the parser to close the element prematurely and discard the trailing content. This could potentially bypass security checks that rely on strict XML well-formedness, leading to data loss or misinterpretation in applications processing untrusted XML input.
