CVE-2026-39922: Geosolutionsgroup Geonode

Medium severity, CVSS 6.3. EPSS: 0.3% chance of exploitation in the next 30 days.

GeoNode versions 4.4.5 and 5.0.2 (and prior within their respective releases) contain a server-side request forgery vulnerability in the service registration endpoint that allows authenticated attackers to trigger outbound network requests to arbitrary URLs by submitting a crafted service URL during form validation. Attackers can probe internal network targets including loopback addresses, RFC1918 private IP ranges, link-local addresses, and cloud metadata services by exploiting insufficient URL validation in the WMS service handler without private IP filtering or allowlist enforcement.

Affected products

• Geosolutionsgroup Geonode: from 4.0.0, before 4.4.5 (fixed in 4.4.5); from 5.0.0, before 5.0.2 (fixed in 5.0.2)
