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 · unedited
A flaw has been found in GeekAI up to 4.2.4. The affected element is the function Download of the file api/handler/net_handler.go. This manipulation of the argument url causes server-side request forgery. Remote exploitation of the attack is possible. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.

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 analysis · high confidence

This is a Server-Side Request Forgery (SSRF) vulnerability in GeekAI up to version 4.2.4. The Download function in api/handler/net_handler.go accepts a user-controlled URL parameter without proper validation, allowing attackers to induce the server to make requests to arbitrary internal or external URLs.

MitigationImplement strict URL validation and allowlisting for the url parameter to restrict requests to trusted domains or IP ranges. Additionally, disable or restrict outbound network requests from the vulnerable endpoint.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Locate GeekAI installation and identify version
    Search for GeekAI installation directories or check the application's version file/config. Common locations may include /opt/geekai, the application root directory, or check for a version indicator in the application startup logs or config file.
    Affected if GeekAI is installed and the version is 4.2.4 or lower
  2. Verify the vulnerable file exists
    Check for the presence of api/handler/net_handler.go in the GeekAI installation directory. This file contains the Download function that handles the URL parameter.
    Affected if The file api/handler/net_handler.go exists and contains a Download function that processes a url parameter
  3. Confirm the Download endpoint is accessible
    Identify if there is an API route that maps to the Download function in net_handler.go. Check the application's routing configuration or API documentation to determine the endpoint path (typically under /api/).
    Affected if An API endpoint for the Download function is exposed and accessible to users
  4. Test if URL parameter lacks validation
    Inspect the source code of net_handler.go to see if the url parameter is validated before being used in an HTTP request. Look for allowlists, validation logic, or sanitization functions before the request is made.
    Affected if The code accepts a user-supplied URL without proper validation or allowlisting logic, or no validation is found in the function
  5. Check network exposure
    Determine if the server can make outbound HTTP requests. This is inherent to the vulnerability but check if the application has any network restrictions configured.
    Affected if The server has the ability to make outbound HTTP requests (default condition for this SSRF to be exploitable)

A user is affected if they are running GeekAI version 4.2.4 or lower with the Download function in api/handler/net_handler.go exposed and accessible, where the url parameter is not validated before use in server-side requests.
