Description

A flaw was found in fast-xml-builder. The software, which builds XML from JSON, incorrectly sanitizes XML comment content. This allows a remote attacker to bypass the sanitization by using three consecutive dashes, enabling them to break out of an XML comment and inject arbitrary XML or HTML content. This could lead to content manipulation or other impacts depending on how the generated XML is processed.
