CVE-2026-39922

GeoNode SSRF via Service Registration

State: Published
Severity: 5.3 Medium
Published: Apr 10, 2026
Updated: Oct 8, 2026
Reserved: Apr 7, 2026

Description

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.
