CVE-2025-58360: GeoServer unauthenticated XXE via WMS GetMap

Exploited in the wild Critical 9.8 EPSS 61.2%

GeoServer accepts XML input on the /geoserver/wms GetMap operation without restricting external entities, so an unauthenticated attacker can read arbitrary files from the server, make server-side requests to internal systems (SSRF) or cause denial of service. Fixed in GeoServer 2.25.6 and 2.26.2; the advisory recommends 2.25.6, 2.26.3 or 2.27.0. CISA added it to KEV on 11 December 2025.

What to do now

Check whether you run the affected software and which version (commands below).
