It was discovered that the StAX XML parser in the JAXP (Java API for XML Processing) component of OpenJDK failed to properly honor setting indicating (defined using isSupportingExternalEntities / IS_SUPPORTING_EXTERNAL_ENTITIES property) whether external XML entities should be processed. External parameter entities were processed even when the StAX parser was configured to not process external entities. An attacker able to provide a specially-crafted XML file to an application using StAX parser could use this flaw to perform XML eXternal Entity (XXE) attack.

IssueDescription: It was discovered that the StAX XML parser in the JAXP component in OpenJDK performed expansion of external parameter entities even when external entity substitution was disabled. A remote attacker could use this flaw to perform XML eXternal Entity (XXE) attack against applications using the StAX parser to parse untrusted XML documents.
