A SSRF vulnerability exists starting in version 3.2.0, bypassing existing controls on the software. This can allow a user to request internal services for a full read SSRF, returning any data from the internal network. The application is using a whitelist, but the whitelist can be bypassed. The bypass will trick the application that the first host is a whitelisted address, but the browser will use `@` or `%40` as a credential to the host geoserver on port 8080, this will return the data to that host on the response. Version 4.1.3.post1 is the first available version that contains a patch.","published":"2023-09-15T20:22:19.102Z","modified":"2026-08-12T03:51:47.115627737Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"PyPI","name":"geonode","fixedVersion":"4.1.3.post1"}],"fix":{"url":"https://github.com/GeoNode/geonode/commit/79ac6e70419c2e0261548bed91c159b54ff35b8d","label":"GeoNode/geonode@79ac6e7"},"references":[{"type":"WEB","url":"https://github.com/GeoNode/geonode/releases/tag/4.1.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/42xxx/CVE-2023-42439.json"},{"type":"ADVISORY","url":"https://github.com/GeoNode/geonode/security/advisories/GHSA-pxg5-h34r-7q8p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-42439"},{"type":"FIX","url":"https://github.com/GeoNode/geonode/commit/79ac6e70419c2e0261548bed91c159b54ff35b8d"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:47.115627737Z"}}
