- Finding
- Unbounded and Incorrectly Quoted Python Dependency Installation## Vulnerability Details **File Location**: `install.sh:12-14` **Vulnerability Type**: Unbounded third-party dependency installation **Risk Level**: Medium ```bash # 安装 Python 依赖 echo "📦 安装 Python 依赖..." pip3 install --user openai>=1.0.0 ``` The same unbounded constraint is declared in `skill.json:19-22`: ```json "dependencies": { "openai": ">=1.0.0" }, ``` ### Technical Analysis The installer does not pin the `openai` dependency to a reviewed version and does not use a lockfile or package integrity hashes. Any future version satisfying the declaration can therefore be installed, making installation non-reproducible and expanding exposure to compromised or malicious future releases. Furthermore, the requirement specifier in the shell command is not quoted. In POSIX-compatible shells, the `>` character is interpreted as an output-redirection operator. Consequently, the shell can parse the command as an unconstrained installation of `openai`, with command output redirected to a file named `=1.0.0`, rather than passing `openai>=1.0.0` as one argument to `pip3`. Python package installation may invoke package build hooks, while imported package code runs with the privileges of the invoking user. Dependency compromise can therefore become local code execution. ### Attack Path 1. An attacker compromises an accepted future release of the dependency or its distribution channel. 2. A user runs `install.sh`. 3. Because the version specifier is unquoted, the shell may install the latest available `openai` release without the intended lower-bound expression being passed to pip. 4. Pip downloads and installs the compromised package without checking a lockfile or expected package hash. 5. Malicious code executes through package installation hooks or when `audio_note_taker.py` imports `OpenAI`. ### Impact Assessment Successful exploitation would permit code execution with the privileges of the user running the in ...[truncated 359 chars]
- Remediation
- ## Remediation Suggestions - Pin the dependency to an exact, reviewed version rather than using an open-ended range. - Quote requirement specifiers passed through a shell: ```bash pip3 install --user 'openai==REVIEWED_VERSION' ``` - Prefer a version-controlled requirements file containing cryptographic hashes: ```text openai==REVIEWED_VERSION \ --hash=sha256:EXPECTED_DISTRIBUTION_HASH ``` Install it with: ```bash python3 -m pip install --user --require-hashes -r requirements.txt ``` - Keep `skill.json`, the installer, and the lockfile synchronized. - Review dependency updates before changing the pinned version. - Install dependencies in an isolated virtual environment rather than modifying the user's general Python environment.
