# GeoServer is an open source server that allows users to share and edit geospatial data

OSGeo GeoServer accepts XML input on the /geoserver/wms GetMap operation without restricting external entities, so an attacker can define external entities in the request. This is an XML external entity (XXE) flaw that CISA lists as actively exploited.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:OSGeo GeoServer affected ? fixed ?
- vendor:geoserver affected < 2.25.6 fixed 2.25.6
- vendor:geoserver affected >= 2.26.0, < 2.26.2 fixed 2.26.2

## Fix

Apply the vendor mitigation per the GeoServer advisory; the sources do not name a fixed version. Discontinue use if no mitigation is available, per CISA guidance.

## From the sources

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.
