Last modified Jun 17, 2026

CVE-2018-19858 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.60% chance of exploitation in the next 30 days.
