CVE-2018-19858 Information

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.
