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 vulnerability was found in PromtEngineer localGPT up to 4d41c7d1713b16b216d8e062e51a5dd88b20b054. This affects the function handle_index of the file rag_system/api_server.py of the component Web Interface. Performing a manipulation results in information disclosure. It is possible to initiate the attack remotely. The exploit has been made public and could be used. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. The vendor was contacted early about this disclosure but did not respond in any way.

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 · moderate confidence

An information disclosure vulnerability exists in the handle_index function of localGPT's web API server (rag_system/api_server.py). The flaw allows remote attackers to potentially access sensitive information through the web interface due to improper handling in the index handler.

MitigationImplement proper access controls and input validation in the handle_index function to prevent unauthorized information disclosure. Review all endpoints in the web interface for similar issues.

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. Verify localGPT installation and version
    Identify if localGPT is installed in your environment by checking for the project directory or installed package. Compare your installed version against the affected version range if known.
    Affected if localGPT is installed and running a version that contains the vulnerable handle_index function in rag_system/api_server.py
  2. Locate the affected API server file
    Find the file rag_system/api_server.py in your localGPT installation directory. This file contains the handle_index function that is vulnerable to information disclosure.
    Affected if The file rag_system/api_server.py exists in your installation and contains the handle_index function
  3. Confirm web API server is running
    Check if the localGPT web API server is currently running. This is typically started via a command like 'python -m rag_system.api_server' or similar startup scripts. Look for listening ports (commonly 8000 or 8080).
    Affected if The web API server is running and accessible over HTTP/HTTPS
  4. Identify if the index endpoint is exposed without authentication
    Inspect the handle_index function in rag_system/api_server.py to determine if it lacks proper authentication checks or access controls before returning sensitive information.
    Affected if The handle_index endpoint can be accessed without authentication and returns sensitive information
  5. Test the endpoint for information disclosure
    If the server is running, send a request to the index-related endpoint (such as /index or similar) without credentials and observe if sensitive data is returned.
    Affected if The endpoint returns sensitive information to unauthenticated users

You are affected if localGPT with the vulnerable handle_index function in rag_system/api_server.py is running and the web API server exposes the index endpoint without proper authentication, allowing unauthorized access to sensitive information.
