OSGeo GeoServer contains an improper restriction of XML external entity reference vulnerability that occurs when the application accepts XML input through a specific endpoint /geoserver/wms operation GetMap and could allow an attacker to define external entities within the XML request.

Added to KEV: 11 Dec 2025Federal remediation due: 1 Jan 2026

Description

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.

How Secuno handles this

Secuno correlates vulnerabilities like CVE-2025-58360 against the real software inventory on every managed device, as each hourly inventory arrives. Rather than a static severity, each match is scored in context: exploit availability, EPSS, the asset's exposure, and business criticality decide where it lands in the queue. Because it is on the CISA KEV list, a risk for it never ranks below high, and the update that fixes it moves to the Emergency patch lane. If an affected version is present anywhere across your portfolio, it surfaces automatically with a prioritised remediation path.
