Directory Traversal in DB-GPT via Python File Upload

Publication date: 2026-09-30

Last updated on: 2026-10-01

Assigner: MITRE

Description

DB-GPT v0.7.5 and v0.8.0 contains directory traversal in python_file_upload (packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/python_upload_api.py:42). A remote attacker can use the validated exploitation path to write files outside the intended workspace or storage boundary.

Exploitability

CWE

KEV

CWE ID	Description
CWE-22	The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Attack-Flow Graph

Executive Summary

DB-GPT versions 0.7.5 and 0.8.0 have a directory traversal vulnerability in the python_file_upload function located in the file python_upload_api.py. This flaw allows a remote attacker to write files outside the intended workspace or storage directory by exploiting a validated path.

Detection Guidance

To detect this vulnerability, inspect the python_file_upload function in packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/python_upload_api.py for improper path validation. Check for file upload endpoints in DB-GPT v0.7.5 or v0.8.0 that allow directory traversal. Monitor logs for unusual file writes outside intended directories.

Impact Analysis

An attacker could exploit this to overwrite critical files, inject malicious code, or gain unauthorized access to sensitive data stored outside the application's intended directory. This may lead to system compromise or data breaches.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's data protection principles or HIPAA's security requirements. Organizations may face legal penalties, loss of trust, and compliance violations due to potential data exposure.

Mitigation Strategies

Upgrade DB-GPT to a version that patches the directory traversal vulnerability in python_file_upload. If no patch is available, disable the python_file_upload functionality or restrict access to the vulnerable API endpoint.
