XML Injection (aka Blind XPath Injection)

CVE-2026-44665

Low
0/10

Summary

fast-xml-builder builds XML from JSON. Prior to version 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.
