Overview
Affected versions of this package are vulnerable to XML Injection via the value() function in src/Toolkit/Xml.php. An attacker can smuggle raw XML markup into generated output by supplying a string that begins with <![CDATA[ but also contains additional text or tags outside a single well-formed CDATA block. This lets attacker-controlled content break out of the intended text node and alter the structure of XML documents produced by the application, leading to malformed output or injected elements in downstream consumers.
