CVE-2026-44665
fast-xml-builder allows attribute values with unwanted quotes to bypass malicious or unwanted attributes
Impact
fast-xml-builder builds XML from JSON. Prior to 1.1.7, when an input data has quotes in attribute values but process entities is not enabled, it breaks the attribute value into multiple attributes. This gives the room for an attacker to insert unwanted attributes to the XML/HTML. This vulnerability is fixed in 1.1.7.
