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."}],"source":{"advisory":"GHSA-x898-729x-cc3r","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-03T17:49:43.605439Z","id":"CVE-2026-58400","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-04T13:42:08.271Z"}}]}}
