Description

A flaw was found in xmldom, a JavaScript module for parsing and serializing XML. The Document.createEntityReference function incorrectly accepts invalid names, which are then directly emitted during serialization. This vulnerability allows an attacker to inject arbitrary XML fragments when an application creates and directly serializes an EntityReference with specific settings. This can lead to the manipulation of XML data when the output is subsequently re-parsed.
