  "summary" : "GeoTools has XML External Entity (XXE) Processing Vulnerability in XSD schema handling",
  "details" : "### Summary\n\nGeoTools Schema class use of Eclipse XSD library to represent schema data structure is vulnerable to XML External Entity (XXE) exploit.\n\n### Impact\n\nThis impacts whoever exposes XML processing with ``gt-xsd-core`` involved in parsing, when the documents carry a reference to an external XML schema. The ``gt-xsd-core`` Schemas class is not using the EntityResolver provided by the ParserHandler (if any was configured).\n\nThis also impacts users of ``gt-wfs-ng`` DataStore where the ENTITY_RESOLVER connection parameter was not being used as intended.\n\n### Resolution\n\nGeoTools API change allows EntityResolver to be supplied to the following methods:\n\n```java\nSchemas.parse( location, locators, resolvers, uriHandlers, entityResolver);\nSchemas.findSchemas(Configuration configuration, EntityResolver entityResolver);\n```\n\nWith this API change the `gt-wfs-ng` WFS DataStore ENTITY_RESOLVER parameter is now used.\n\n### Reference\n\n* [GHSA-jj54-8f66-c5pc](https://github.com/geoserver/geoserver/security/advisories/GHSA-jj54-8f66-c5pc): Describes the impact of the ``gt-xsd-core`` vulnerability on the GeoServer WFS protocol, resulting in both Service Side Request Forgery (SSRF) and Out-of-Band (OOB) data exfiltration of local files.\n\n* [GHSA-2p76-gc46-5fvc](https://github.com/geonetwork/core-geonetwork/security/advisories/GHSA-2p76-gc46-5fvc): Describes the impact of the ``gt-wfs-ng`` and ``gt-xsd-core`` vulnerability on the GeoNetwork WFS Index functionality.",
