CVE-2026-102495
Published:September 29, 2026
Updated:October 09, 2026
Apache XmlSchema doesn't limit how deeply schema imports and includes can be nested, so a malicious schema can make parsing recurse until the stack overflows. This causes a denial of service.
Users are recommended to upgrade to version 2.3.3, which fixes this issue.
