A flaw was found in Wildfly’s implementation of Xerces, specifically in the way the XMLSchemaValidator class in the JAXP component of Wildfly enforced the “use-grammar-pool-only” feature. This flaw allows a specially-crafted XML file to manipulate the validation process in certain cases. This issue is the same flaw as CVE-2020-14621, which affected OpenJDK, and uses a similar code. All xerces jboss versions before 2.12.0.SP3.
