- Unpinned and Unnecessary Third-Party Dependencies<![CDATA[ ## Vulnerability Details **File Location**: `SKILL.md:48` and `scripts/search.py:51` **Vulnerability Type**: Uncontrolled third-party dependency resolution and unnecessary dependency exposure **Risk Level**: Medium ### Vulnerable Code `SKILL.md:48`: ```bash pip install aliyun-python-sdk-core requests ``` Related unused import in `scripts/search.py:51`: ```python import requests ``` ### Technical Analysis The installation instructions request `aliyun-python-sdk-core` and `requests` without specifying reviewed versions or package hashes. Consequently, package resolution depends on whichever releases the configured Python package index serves at installation time. The effective installed code can therefore change after this Skill has been reviewed. A compromised upstream release, package-index compromise, or unsafe index configuration could cause malicious package installation or import-time code to execute with the privileges of the user installing or running the Skill. The `requests` package is imported but never used, meaning it expands the supply-chain and transitive-dependency attack surface without supporting the implemented Alibaba Cloud SDK request flow. This finding does not establish that the currently published packages are malicious. The vulnerability is the absence of dependency integrity controls and the inclusion of an unnecessary dependency. ### Attack Path 1. An attacker compromises an allowed dependency release or the package index used by the victim, or influences dependency resolution through an unsafe package-index configuration. 2. A user follows the documented command: ```bash pip install aliyun-python-sdk-core requests ``` 3. `pip` resolves and installs the attacker-controlled package version because no exact version or cryptographic hash is required. 4. Malicious installation hooks or package code execute with the installing user's privileges. 5. If malicious code remains in the installed package, it may execu ...[truncated 628 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Remove `requests` from the installation instructions and delete its unused import from `scripts/search.py`. 2. Pin every required direct and transitive dependency to a reviewed version in a lock file. 3. Require cryptographic hashes during installation, for example by maintaining a hash-locked requirements file and installing it with: ```bash python -m pip install --require-hashes -r requirements.txt ``` 4. Generate dependency locks from a trusted package index and review package names carefully to prevent typosquatting or dependency confusion. 5. Use an isolated virtual environment and avoid installing the Skill as a privileged or administrative user. 6. Add automated dependency vulnerability and provenance checks to the release process, and update pinned versions only after review and testing. ]]>
