- Unpinned DashScope SDK Installation Creates a Supply-Chain Risk## Vulnerability Details **File Location**: `SKILL.md`, lines 15–19 **Vulnerability Type**: Unpinned third-party dependency **Risk Level**: Medium **Vulnerable Code**: ```bash python3 -m venv .venv . .venv/bin/activate python -m pip install dashscope ``` ### Technical Analysis The installation command retrieves the latest available `dashscope` package without an exact version constraint or integrity hash. Consequently, the dependency installed during a future Skill invocation may differ from the dependency that was previously reviewed. If the package publisher account, package repository, or a future upstream release is compromised, following this prerequisite could introduce malicious package code. Creating and using a virtual environment limits changes to the Python environment, but it does not sandbox the package: installation hooks and subsequently imported code execute with the privileges of the user running the command. ### Attack Path 1. An attacker compromises the upstream package, its publisher account, or the package distribution channel. 2. The attacker publishes a malicious release under the legitimate `dashscope` package name. 3. A user follows the Skill prerequisite and runs `python -m pip install dashscope`. 4. Pip resolves and downloads the compromised mutable release because no version or hash is enforced. 5. Malicious installation-time or runtime code executes with the invoking user's privileges. 6. That code can access resources available to the process, potentially including project files, environment variables such as `DASHSCOPE_API_KEY`, and user-readable credential files. ### Impact Assessment Successful exploitation could result in arbitrary code execution under the invoking user's account. The accessible scope includes files, environment variables, network access, and credentials available to that user and process. The instruction does not request elevated operating-system privileges, so ...[truncated 491 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `dashscope` to an exact, reviewed version rather than installing an unconstrained latest release. 2. Record dependencies in a lock file or requirements file containing cryptographic hashes. 3. Enforce hash verification during installation, for example: ```bash python -m pip install --require-hashes -r requirements.txt ``` 4. Obtain package artifacts only from an explicitly trusted package index and consider maintaining an internally reviewed mirror. 5. Review dependency updates before changing the pinned version and use automated software-composition analysis. 6. Run the SDK with the minimum required filesystem and network permissions. 7. Prefer passing `DASHSCOPE_API_KEY` only to the process that needs it, and ensure logs and generated evidence files redact authorization headers, API keys, and other secrets.
