Improper Input Validation in Xerces
Quick fix
GHSA-w4jq-qh47-hvjq — xerces:xercesImpl: upgrade to the fixed version with the command below.
# pom.xml: bump <version>2.12.0.sp3</version> for xerces:xercesImplDetails
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.
