NVD Description

Note: Versions mentioned in the description apply only to the upstream eap7-wildfly package and not the eap7-wildfly package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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. This flaw affects all Xerces JBoss versions before 2.12.0.SP3.
