Prior to versions 4.4.12 and 4.2.17, the Saxon XSLT processor used to render formatters is configured without secure processing (`FEATURE_SECURE_PROCESSING`) and without disabling Java extension functions (`ALLOW_EXTERNAL_FUNCTIONS`). Any stylesheet loaded by GeoNetwork can therefore invoke\n`java.lang.Runtime.exec()` or `java.lang.ProcessBuilder` directly, achieving arbitrary command execution as the GeoNetwork process user. A user with sufficient privileges to upload a formatter can deliver a `.xsl` file containing Java extension call that execute arbitrary OS commands with the privileges of the GeoNetwork process. The issue is patched in GeoNetwork versions 4.4.12 and 4.2.17."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"geonetwork","product":"core-geonetwork","versions":[{"version":">= 4.3.0, < 4.4.12","status":"affected"},{"version":"< 4.2.17","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","baseScore":9.1,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.3,"impactScore":6.0}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-09-03T17:49:43.605439Z","id":"CVE-2026-58400","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-94"},{"lang":"en","value":"CWE-470"}]}],"references":[{"url":"https://docs.geonetwork-opensource.org/4.2/overview/change-log/version-4.2.17","source":"security-advisories@github.com"},{"url":"https://docs.geonetwork-opensource.org/4.4/overview/change-log/version-4.4.12","source":"security-advisories@github.com"},{"url":"https://github.com/geonetwork/core-geonetwork/security/advisories/GHSA-x898-729x-cc3r","source":"security-advisories@github.com"},{"url":"https://thehackernews.com/2026/09/geonetwork-fixes-unauthenticated-rce.html","source":"security-advisories@github.com"}]}}]}
