CVE-2023-26043
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedGeoNode is an open source platform that facilitates the creation, sharing, and collaborative use of geospatial data. GeoNode is vulnerable to an XML External Entity (XXE) injection in the style upload functionality of GeoServer leading to Arbitrary File Read. This issue has been patched in version 4.0.3.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisAn XML parser processes external entity references inside untrusted documents, letting an attacker read local files, reach internal systems, or exhaust resources. It's a common trap in anything that accepts XML. The fix is to disable external entities and DTD processing in the parser.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.0.3
Geonode 4.0.3 or later
- Identify the current installed Geonode version using package manager or docker image tag
- Stop any running Geonode services to prevent data corruption during upgrade
- Backup the existing Geonode database, uploaded data, and configuration files
- For Docker-based installations: Update the image tag to 4.0.3 or later in docker-compose.yml or .env file, then pull the new image and recreate containers
- For pip-based installations: Run `pip install geonode==4.0.3` or `pip install --upgrade geonode>=4.0.3`
- For package-based installations: Update via system package manager (e.g., apt-get update && apt-get install geonode)
- Verify the upgrade was successful by checking the Geonode version endpoint or admin interface
- Review Geonode 4.0.3 release notes for any additional post-upgrade migration steps
