Associated Vulnerability
Title:GeoServer is vulnerable to an Unauthenticated XML External Entities (XXE) attack via WMS GetMap feature (CVE-2025-58360)
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.
Description
GeoServer 2.26.0 to 2.26.2 and 2.25.6 contains an XML External Entity (XXE) injection caused by insufficient sanitization of XML input in /geoserver/wms GetMap operation, letting attackers disclose files or cause DoS, exploit requires crafted XML input.
