CVE-2026-51863 · Severity: info · Published 2026-10-29

DB-GPT is an AI database assistant platform. A directory traversal vulnerability in the example file upload API allows authenticated users to write files outside the intended storage boundary, potentially enabling arbitrary file write attacks. An attacker could overwrite critical files or place backdoors on the system if the example files dictionary is compromised through configuration injection or database manipulation.

## Technical details

The use_example_file endpoint in examples_api.py validates the example_id against a whitelist but fails to validate the example["name"] field for path traversal sequences like "..", allowing attackers to construct paths that escape the user's upload directory. The vulnerability requires either authentication or control over the EXAMPLE_FILES dictionary through configuration injection or database manipulation. A successful exploit enables arbitrary file write to any location the application process has write permissions.
