# DB-GPT: directory traversal lets remote users write files outside workspace

DB-GPT versions 0.7.5 and 0.8.0 have a directory traversal flaw in the use_example_file function of its examples API. A remote attacker can write files outside the intended workspace or storage directory.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- pip:DB-GPT affected 0.7.5, 0.8.0 fixed ?

## How to check

- Check the installed DB-GPT version (`dbgpt --version` or the package version in `packages/dbgpt-app`) and see whether it is `0.7.5` or `0.8.0`.
- Look at `packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/examples_api.py` around line 129 to confirm the file-path handling in `use_example_file`.

## Timeline

- 2026-10-29T18:26:33+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-51863
- 2026-10-29T18:30:51+00:00 analyst — Reporter issue #3028 (closed; referenced by PR #3066 'validate example file names') shows the traversal is via example['name'] from the EXAMPLE_FILES dict, not a request parameter; endpoint POST /api/v1/examples/use needs the user_id header dependency (which sibling CVEs say is a mock granting admin). The issue's PoC requires tampering with EXAMPLE_FILES, so practical exploitability looks low. No vendor advisory or fixed release found; PR page unreadable, so the fix version is unknown. Severity left unchanged. Settle it by checking whether PR #3066 is merged and which release contains it.

## From the sources

DB-GPT v0.7.5 and 0.8.0 contains directory traversal in use_example_file (packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/examples_api.py:129). A remote attacker can use the validated exploitation path to write files outside the intended workspace or storage boundary.
