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. A specially-crafted XML file could possibly use this flaw to manipulate with the validation process in certain cases. This is the same flaw as CVE-2020-14621, which affected OpenJDK, which uses similar code.
