The short answer
CVE-2025-58360 affects geoserver geoserver and is rated critical (CVSS 9.8). CISA added it to the Known Exploited Vulnerabilities catalog on 2025-12-11: attackers are using it, so patch it first. Fixed versions are published for gs-web-app (2.26.2, 2.25.6) and gs-wms (2.26.2, 2.25.6).
What it is
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.
Weakness: CWE-611.
