{"id":"PYSEC-2026-61","details":"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.","aliases":["CVE-2026-39922","GHSA-hw9r-6m78-w6h3"],"modified":"2026-05-20T09:19:01.185236Z","published":"2026-04-10T20:16:22.270Z","references":[{"type":"ADVISORY","url":"https://github.com/GeoNode/geonode/security/advisories/GHSA-hw9r-6m78-w6h3"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/geonode-ssrf-via-service-registration"}],"affected":[{"package":{"name":"geonode","ecosystem":"PyPI","purl":"pkg:pypi/geonode"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.4.5"},{"introduced":"5.0.0"},{"fixed":"5.0.2"}]}],"versions":["4.0.0","4.0.0.post1","4.0.1","4.0.2","4.0.3","4.1.0","4.1.1","4.1.2","4.1.3","4.1.3.post1","4.1.4","4.1.5","4.2.0","4.2.1","4.2.2","4.2.3","4.2.4","4.2.5","4.3.0","4.3.0.post1","4.3.1","4.4.0","4.4.1","4.4.2","4.4.3","4.4.4","5.0.0","5.0.1"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/geonode/PYSEC-2026-61.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"}]}
