Last modified

CVE-2026-39922 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
