# CVE-2025-58360: OSGeo GeoServer Improper Restriction of XML External Entity Reference Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run OSGeo GeoServer. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-12-11, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-01-01 ; treat that as the outer limit, not the target.
- EPSS 60.0% , percentile 99: FIRST’s model estimates a 60.0% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

## What it is

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.

## Affected products (CVE record)

- geoserver geoserver: >= 2.26.0, < 2.26.2, < 2.25.6

## Severity

- GitHub_M CVSS 3.1: 8.2 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L`

## Exploitation

- CISA KEV: added 2025-12-11; federal due date 2026-01-01. Known ransomware use: Unknown.
- CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 60.01% probability of exploitation activity in the next 30 days; percentile 99.
