CVE-2026-58400
Published:September 03, 2026
Updated:September 22, 2026
GeoNetwork is a catalog application to manage spatially referenced resources. 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
"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.
