GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. The WMS specification defines an ``sld=<url>`` parameter for GetMap, GetLegendGraphic and GetFeatureInfo operations for user supplied "dynamic styling". Enabling the use of dynamic styles, without also configuring URL checks, provides the opportunity for Service Side Request Forgery. This vulnerability can be used to steal user NetNTLMv2 hashes which could be relayed or cracked externally to gain further access. This vulnerability has been patched in versions 2.22.5 and 2.23.2.

 https://cve.radiocsirt.org/vuln/ghsa-cqpc-x2c6-2gmf GHSA-cqpc-x2c6-2gmf — Unsecured WMS dynamic styling sld=<url> parameter affords blind unauthenticated SSRF 2026-10-20T11:29:19.527344+00:00

Affected: Maven: org.geoserver:gs-wms, Maven: org.geoserver.web:gs-web-app

### Summary

The WMS specification defines an ``sld=<url>`` parameter for GetMap, GetLegendGraphic and GetFeatureInfo operations for user supplied "dynamic styling". Enabling the use of dynamic styles, without also configuring URL checks, provides the opportunity for Service Side Request Forgery. It is possible to use this for "Blind SSRF" on the WMS endpoint to steal NetNTLMv2 hashes via file requests to malicious servers.

### Details

This vulnerability requires:

* WMS Settings dynamic styling being enabled * Security URL checks to be disabled, or to be enabled and allowing ``file:\\*`` access

### Impact

This vulnerability can be used to steal user NetNTLMv2 hashes which could be relayed or cracked externally to gain further access.

### Mitigation

The ability to reference an external URL location is defined by the WMS standard GetMap, GetFeatureInfo and GetLegendGraphic operations. These operations are defined by an Industry and International standard and cannot be redefined by the GeoServer application in isolation.

To disable dynamic styling on GeoServer 2.10.3 and GeoServer 2.11.1:

1. Navigate to **Services > WMS Settings** page 2. Locate **Dynamic styling** heading 3. Select the **Disable usage of SLD and SLD_BODY parameters in GET requests and user styles in POST** checkbox.

### Resolution

To allow dynamic styling safely on GeoServer 2.22.5 and GeoServer 2.23.2:

1. Navigate to **Security > URL Checks** 2. Enable **URL Checks are enabled** setting 3. Chec…
