CVE-2026-33050 in GeoNode
Summary
by MITRE • 11/06/2026
GeoNode is a geospatial content management system, a platform for the management and publication of geospatial data. Prior to 5.1.0, a crafted vector file layer name supplied during upload allows a low-privileged remote user to inject shell syntax and execute arbitrary operating-system commands on the GeoNode server. This issue is fixed in version 5.1.0.

GeoNode serves as a comprehensive geospatial content management system designed for the efficient handling, publication, and visualization of geographic data. It provides organizations with the infrastructure to manage complex spatial datasets while facilitating collaboration among users who require access to location-based information. The platform relies heavily on robust input validation mechanisms when processing user-supplied files, particularly during the upload process where vector file layers are ingested into the system for further analysis or display.
A critical security vulnerability existed in versions of GeoNode prior to 5.1.0 that allowed low-privileged remote users to execute arbitrary operating-system commands on the server hosting the application. This flaw was rooted in insufficient sanitization of layer names provided during the upload of vector files. When a user submitted a file, the system accepted the associated metadata, including the name assigned to the new layer. The vulnerability arose because this input field did not adequately filter or escape special characters that are interpreted by underlying shell commands used for processing geospatial data formats such as Shapefiles or GeoJSON.
By crafting a vector file with a specifically designed layer name containing shell metacharacters, an attacker could inject malicious syntax into the command string executed by the server-side processes. This technique leverages OS Command Injection vulnerabilities, where untrusted input is passed directly to system-level commands without proper validation. The impact of this flaw was severe because it effectively bypassed authentication and authorization controls for basic user accounts. A remote adversary with minimal privileges could escalate their access level significantly, gaining the ability to run arbitrary code with the permissions of the web application process.
The operational impact of such a vulnerability extends beyond simple data compromise. Successful exploitation allows an attacker to read sensitive configuration files, modify or delete critical geospatial datasets, and potentially use the compromised server as a pivot point for further attacks within the internal network. This undermines the integrity and availability of the entire geospatial infrastructure managed by GeoNode. The ability to execute commands remotely means that attackers could install backdoors, exfiltrate data, or disrupt services entirely, leading to significant downtime and loss of trust in the platform's reliability.
This vulnerability is classified under CWE-78 Improper Neutralization of Special Elements used in an OS Command, commonly known as OS Command Injection. It aligns with MITRE ATT&CK techniques related to Execution via Remote Services or Command Line Interface exploitation, specifically highlighting how application-level flaws can lead to direct system compromise. The root cause lies in the failure to implement strict input validation and output encoding for data that interacts directly with operating system utilities during file processing workflows.
Mitigation strategies primarily involve upgrading to GeoNode version 5.1.0 or later, where this issue has been resolved through improved sanitization routines. For organizations unable to upgrade immediately, implementing a web application firewall can help detect and block requests containing suspicious shell metacharacters in upload parameters. Additionally, enforcing strict file type validation and restricting the execution permissions of the user account running the GeoNode service can reduce the potential impact if an exploit is attempted. Regular security audits focusing on input handling in geospatial data ingestion modules are recommended to prevent similar vulnerabilities from being introduced during future development cycles.
