Xerces2 is the next generation of high performance, fully compliant XML parsers in the
Apache Xerces family. This new version of Xerces introduces the Xerces Native Interface (XNI),
a complete framework for building parser components and configurations that is extremely
modular and easy to program.
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.
:heavy_check_mark: This issue was automatically closed by Mend because the vulnerable library in the specific branch(es) was either marked as ignored or it is no longer part of the Mend inventory.
