Technical description

PrinceXML, versions 10 and below, is vulnerable to XXE due to the lack of protection against external entities. If an attacker passes HTML referencing an XML file (e.g., in an IFRAME element), PrinceXML will fetch the XML and parse it, thus giving an attacker file-read access and full-fledged SSRF.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
