CVE-2025-58360: GeoServer is vulnerable to an Unauthenticated XML External Entities (XXE) attack via WMS GetMap feature

Noroxi assessment

Priority: Now (action score 87/100)

  • CISA has confirmed exploitation in the wild (Dec 11, 2025). Remediation deadline for US federal agencies: Jan 1, 2026.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 61.1% (FIRST EPSS); higher than 99.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: org.geoserver:gs-wms (Maven) 2.26.2, 2.25.6; org.geoserver.web:gs-web-app (Maven) 2.26.2, 2.25.6.

Patch today or shut off access. Upgrade to org.geoserver:gs-wms (Maven) 2.26.2, 2.25.6; org.geoserver.web:gs-web-app (Maven) 2.26.2, 2.25.6 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

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.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Dec 11, 2025. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Jan 1, 2026.
