Code injection in the Lutece Core

Published Sep 1, 2026 · Updated Sep 1, 2026 · Assigned by INCIBE

Vendor: Lutece Product: Lutece Core

Description

A vulnerability in the Lutece Core XSL export management module up to version 7.1.7, which allows authenticated administrators to execute code remotely. The XML/XSLT processing configuration does not enable secure processing mode (FEATURE_SECURE_PROCESSING), allowing Java extension functions to be executed from malicious XSL stylesheets. An attacker with administrator privileges can upload a manipulated XSL transformation file and trigger its execution during user export operations, resulting in the execution of arbitrary code on the server.
