Description

A flaw was found in fast-xml-builder, a software component used to create XML documents from JSON data. This vulnerability allows a remote attacker to inject unauthorized attributes into the generated XML or HTML output. By crafting malicious input that includes quotes in attribute values without proper entity processing, an attacker can manipulate the structure of the output. This could lead to unintended information disclosure or alteration of how content is displayed.
