- Finding
- Unpinned Third-Party Dependency Installation Guidance<![CDATA[ ## Vulnerability Details **File Location**: `scripts/rewrite_client.py:11-14` **Vulnerability Type**: Unpinned third-party dependency **Risk Level**: Low ### Vulnerable Code ```python try: from openai import OpenAI except ImportError as exc: # pragma: no cover raise SystemExit("缺少 openai 依赖，请先安装 openai：pip install openai") from exc ``` ### Technical Analysis When the `openai` module is unavailable, the script instructs the user to execute `pip install openai` without specifying a reviewed version or enforcing package-integrity hashes. This causes the installed dependency version to be selected dynamically from the configured Python package index. The project does not include a lock file or dependency manifest that constrains the OpenAI SDK to a known, audited version. Consequently, runtime behavior may differ from the behavior assessed during this audit. The issue is conditional on a user or deployment process following the installation guidance; the script does not automatically install or execute a remotely retrieved package. ### Attack Path 1. The user runs the script in an environment where the `openai` package is absent. 2. The import fails, and the script recommends running `pip install openai`. 3. The user executes that command without a pinned version or integrity verification. 4. The package installer retrieves whichever version is currently selected by the configured package index. 5. If the package source, index configuration, account, or selected release has been compromised, attacker-controlled code can execute during installation, import, or subsequent SDK use. 6. Such code executes with the privileges of the user running the installation or script. ### Impact Assessment A compromised dependency would run with the invoking user's privileges. Within that scope, it could potentially: - Read `IME_MODEL_API_KEY` and other environment variables. - Access message text submitted for rewriting. - Read or modify files availabl ...[truncated 351 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Add a dependency manifest and pin the OpenAI SDK to a reviewed version, for example: ```text openai==<reviewed-version> ``` 2. Generate and verify cryptographic hashes for production installations, such as by using a hash-locked requirements file with: ```bash pip install --require-hashes -r requirements.txt ``` 3. Commit a lock file generated by the project's selected dependency-management tool and review dependency updates before deployment. 4. Install packages only from an explicitly trusted package index, preferably in an isolated virtual environment. 5. Replace the unconstrained installation message with instructions that reference the project's locked dependency file, for example: ```text Install the reviewed dependencies with: pip install --require-hashes -r requirements.txt ``` 6. Add automated dependency and supply-chain scanning to CI, and verify package provenance where supported. ]]>
