CVE-2026-2253Network attack vector

Authenticated SSRF via external entity resolution

Published May 27, 2026 · Updated May 27, 2026

XXE in Pentaho Data Integration and Analytics before 10.2.0.7 and 11.0.0.0 allows remote authenticated users to trigger SSRF. Certain XML parsers resolve external entities declared in an attacker-supplied DTD and issue outbound requests to entity URIs. Low-privileged network access is required; resulting server-side requests can reach otherwise inaccessible services, bypass firewall restrictions, or conduct port scanning.
