- Unpinned Third-Party SDK Installation Creates Supply-Chain Risk## Vulnerability Details **File Location**: `SKILL.md`, lines 21-27 **Vulnerability Type**: Unpinned third-party dependency **Risk Level**: Medium ```bash - Install SDK in a virtual environment: ```bash python3 -m venv .venv . .venv/bin/activate python -m pip install dashscope ``` ``` ### Technical Analysis The installation instructions retrieve the latest available `dashscope` package and its transitive dependencies without specifying reviewed versions or verifying package hashes. Consequently, the code installed by this command may differ between executions and may change after the Skill itself has been audited. The package name is consistent with the declared Alibaba Cloud integration, and there is no evidence that the Skill intentionally references a malicious or misspelled package. However, an unpinned installation remains exposed to upstream package compromise, compromised transitive dependencies, malicious release replacement, and unexpected security or compatibility regressions. The use of a virtual environment limits modification of the global Python environment, but it does not sandbox package installation or execution. Package build hooks and subsequently imported SDK code execute with the operating-system permissions of the user running the command. ### Attack Path 1. An attacker compromises the `dashscope` distribution account, one of its transitive dependencies, or the relevant package-distribution infrastructure. 2. The attacker publishes a malicious release that satisfies the unrestricted dependency request. 3. A user follows the documented `python -m pip install dashscope` instruction. 4. Pip resolves and downloads the attacker-controlled release or dependency. 5. Malicious installation hooks or runtime code execute with the invoking user's privileges. 6. Depending on those privileges, the payload could access local files, environment variables such as `DASHSCOPE_API_KEY`, Alibaba Cloud credent ...[truncated 742 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `dashscope` to an explicitly reviewed version, for example: ```bash python -m pip install "dashscope==<reviewed-version>" ``` 2. Pin all transitive dependencies through a reviewed lock file generated with a dependency-management tool such as `pip-tools`. 3. Record cryptographic hashes and install with hash enforcement: ```bash python -m pip install --require-hashes -r requirements.txt ``` 4. Configure pip to use an approved package index and avoid untrusted extra indexes. 5. Periodically scan the locked dependency set for known vulnerabilities and review dependency updates before changing pins. 6. Continue using an isolated virtual environment and avoid installing or executing the SDK with root or administrator privileges. 7. Prefer `DASHSCOPE_API_KEY` through a narrowly scoped process environment, apply least-privilege cloud permissions, and ensure credential files have restrictive filesystem permissions.
