This vulnerability requires:
- The WPS extension to be installed
- The WPS security setting "Disable complex inputs" to be unselected
- Security URL checks to be disabled

This vulnerability presents the opportunity for Server Side Request Forgery.
Mitigation
The ability to reference an external URL location is defined by the WPS standard Execute operation. This operations is defined by an Industry and International standard and cannot be redefined by the GeoServer application in isolation.

Resolution
To allow processing of complex inputs safely in GeoServer 2.22.5 and GeoServer 2.23.2:
