High · 8.2 Known exploited Scanner template Public exploit CVE-2025-58360 EUVD-2025-199606GHSA-fjf5-xgmq-5525

GeoServer is vulnerable to an Unauthenticated XML External Entities (XXE) attack via WMS GetMap feature

Published Nov 25, 2025 · Updated Feb 26, 2026 · Assigned by GitHub_M

Description

GeoServer is an open source server that allows users to share and edit geospatial data. From version 2.26.0 to before 2.26.2 and before 2.25.6, an XML External Entity (XXE) vulnerability was identified. The application accepts XML input through a specific endpoint /geoserver/wms operation GetMap. However, this input is not sufficiently sanitized or restricted, allowing an attacker to define external entities within the XML request. This issue has been patched in GeoServer 2.25.6, GeoServer 2.26.3, and GeoServer 2.27.0.
