| Titel | dexhunter kaggle-mcp 0.1.0 Path Traversal |
|---|
| Beschreibung | The prepare_kaggle_dataset tool expects competition_id to be a Kaggle competition slug, but it uses that value directly as a filesystem path component when creating the local extraction directory:
data_dir = Path(__file__).parent / "data" / arguments["competition_id"]
os.makedirs(data_dir, exist_ok=True)
Because no slug validation, canonicalization, or root-boundary check is applied, traversal sequences such as ../../../../tmp/poc escape the intended src/kaggle_mcp/data/ tree. The directory is created before Kaggle API download or extraction occurs, so the path traversal is reachable even when the later download fails.
