{"id":"CVE-2026-4813","state":"PUBLISHED","title":"Code injection in the 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.","publishedAt":"2026-09-01T10:54:03.566Z","updatedAt":"2026-09-01T12:17:12.913Z","severity":{"score":9.4,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","source":"INCIBE"},"assigner":"INCIBE","products":["Lutece Lutece Core"],"affected":[{"vendor":"Lutece","product":"Lutece Core","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"7.1.7","versionType":"custom"}]}],"references":["http://incibe.es/en/incibe-cert/notices/aviso/code-injection-lutece-core"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4813.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4813","state":"PUBLISHED","datePublished":"2026-09-01T10:54:03.566Z","dateUpdated":"2026-09-01T12:17:12.913Z","assignerShortName":"INCIBE","assignerOrgId":"0cbda920-cd7f-484a-8e76-bf7f4b7f4516","dateReserved":"2026-03-25T13:08:57.318Z"},"containers":{"cna":{"title":"Code injection in the Lutece Core","descriptions":[{"lang":"en","value":"A vulnerability in the Lutece Core XSL export management module up to version 7.1.7, which allows authenticated administrators to execute code remotely.
