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.
Summary dbcve.org
GeoServer contains an XML External Entity (XXE) vulnerability in the WMS GetMap endpoint (/geoserver/wms). The application accepts unsanitized XML input, allowing attackers to define external entities that can be used for file disclosure, SSRF, or denial of service. Versions 2.26.0 through 2.26.1 and 2.25.0-2.25.5 are affected.
Mitigation
Upgrade to GeoServer 2.25.6, 2.26.3, or 2.27.0 or later, which contain proper XML input sanitization to prevent XXE attacks.
