CVE-2024-2374Network attack vector

File disclosure and denial of service via XXE

Published Apr 16, 2026 · Updated Apr 16, 2026

XXE in multiple WSO2 server products allows remote attackers to read local files or access limited HTTP resources through crafted XML. Their XML parsers process user-supplied XML while external entity resolution remains enabled, causing referenced local or HTTP resources to be included. No authentication or user interaction is required; recursive entities or large external resources can also exhaust server resources and interrupt service.
