CISA added CVE-2025-58360, a high-severity XML External Entity (XXE) vulnerability in OSGeo GeoServer, to its Known Exploited Vulnerabilities catalog due to evidence of active exploitation. The unauthenticated flaw has a CVSS score of 8.2 and affects all GeoServer versions prior to an unspecified version. The vulnerability allows attackers to exploit XXE weaknesses without authentication, posing significant risk to organizations running vulnerable GeoServer instances.
Technical details
CVE-2025-58360 is an unauthenticated XML External Entity (XXE) vulnerability with CVSS score 8.2. The flaw occurs when the application accepts XML input through the /geoserver/wms operation GetMap endpoint, allowing attackers to define external entities within XML requests. Successful exploitation enables access to arbitrary files from the server's file system, Server-Side Request Forgery (SSRF) to interact with internal systems, or denial-of-service (DoS) attacks by exhausting resources.
Mitigation steps:
Update to patched versions: 2.25.6, 2.26.2, 2.27.0, 2.28.0, or 2.28.1. Federal Civilian Executive Branch (FCEB) agencies must apply required fixes by January 1, 2026.
Affected products:
OSGeo GeoServer versions prior to and including 2.25.5
OSGeo GeoServer versions 2.26.0 through 2.26.1
