CVE-2025-27511Network attack vector

Administrator RCE via unrestricted DB2 JNDI lookup

Published Jun 18, 2026 · Updated Jun 18, 2026

JNDI injection in GeoServer DB2 DataStore Extension before 2.27.0 allows remote authenticated users to execute arbitrary code via a DB2 JDBC URL. The Vector Data Sources store-creation path accepts unrestricted DB2 connection parameters and resolves the attacker-supplied JDBC URL through JNDI, enabling untrusted object deserialization. Administrative access and an installed DB2 extension are required; successful exploitation runs code with the GeoServer process privileges.
