GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. The OGC Web Processing Service (WPS) specification is designed to process information from any server using GET and POST requests. This presents the opportunity for Server Side Request Forgery. This vulnerability has been patched in version 2.22.5 and 2.23.2.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
