CVE-2026-51864 · Severity: info · Published 2026-09-30

DB-GPT is an open-source AI database assistant that allows uploading Python files for data processing and analysis. A directory traversal vulnerability in the file upload endpoint allows attackers to write arbitrary files outside the intended workspace, potentially overwriting system files or injecting malicious code into the application.

## Technical details

The python_file_upload endpoint in python_upload_api.py fails to properly validate file paths, allowing attackers to use path traversal sequences (e.g., ../) to write files outside the intended upload directory. An unauthenticated remote attacker can exploit this via a crafted upload request to achieve arbitrary file write on the server, potentially leading to code execution or data compromise depending on file permissions and application logic.
