Description

A flaw was found in xmldom, a JavaScript module for parsing and serializing XML. An attacker can exploit a vulnerability in how processing instructions are handled to inject arbitrary XML structures. This occurs because the software fails to properly validate input, allowing special characters to bypass security checks. Successful exploitation could lead to data manipulation or other integrity impacts within applications processing the affected XML.
