CVE-2026-4813 is a CWE-94 code-injection vulnerability in the Lutece Core XSL export-management module through version 7.1.7. Its XML/XSLT processor is configured without FEATURE_SECURE_PROCESSING, allowing malicious XSL stylesheets to invoke Java extension functions. An authenticated administrator can upload a crafted XSL transformation and cause it to be processed during a user export operation, executing arbitrary code in the server-side application context.
