- Unpinned Third-Party Dependency Installation## Vulnerability Details **File Location**: `SKILL.md`, lines 44–49 **Vulnerability Type**: Unpinned package installation and software supply-chain exposure **Risk Level**: Medium **Vulnerable Code Snippet**: ```bash python3 -m venv .venv . .venv/bin/activate python -m pip install dashscope ``` ```text - Set `DASHSCOPE_API_KEY` in your environment, or add `dashscope_api_key` to `~/.alibabacloud/credentials`. ``` ### Technical Analysis The Skill instructs users to install `dashscope` from the active Python package index without specifying an audited version, lock file, package hash, or trusted index. Although this SDK is relevant to the declared Alibaba Cloud image-editing functionality, an unrestricted installation resolves whichever release the package index currently presents. Python package installation may execute package-controlled build or installation logic. Therefore, compromise of the legitimate package, its publisher account, the configured package index, or the dependency resolution chain could result in arbitrary local code execution during installation. The absence of version and integrity constraints also makes installation non-reproducible and prevents users from verifying that they are installing the same artifact that was reviewed. The nearby credential instruction increases the potential consequence because the user environment may contain `DASHSCOPE_API_KEY`, and the documented alternative credential file is `~/.alibabacloud/credentials`. However, the audited project code does not itself read, print, store, or transmit either credential source. The credential configuration is functionally necessary for authenticated provider access and does not independently constitute unauthorized access. ### Attack Path 1. A user follows the Skill prerequisite and activates a local virtual environment. 2. The user runs `python -m pip install dashscope`. 3. Pip queries the user's configured package index and re ...[truncated 1167 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `dashscope` to a specific version that has been reviewed and tested: ```bash python -m pip install "dashscope==<reviewed-version>" ``` 2. Generate a lock or requirements file containing cryptographic hashes and install it with hash enforcement: ```bash python -m pip install --require-hashes -r requirements.txt ``` 3. Pin and review all transitive dependencies rather than constraining only the top-level package. 4. Explicitly document and enforce the expected trusted package index instead of relying on arbitrary user-level pip configuration. 5. Perform dependency vulnerability and provenance checks during release preparation. 6. Install dependencies before placing cloud credentials in the process environment where practical, and avoid exposing long-lived credentials to package installation processes. 7. Use narrowly scoped, short-lived provider credentials and restrictive filesystem permissions for `~/.alibabacloud/credentials`.
