- Unpinned Third-Party Python Dependencies<![CDATA[ ## Vulnerability Details **File Location**: `README.md:83-87` **Vulnerability Type**: Unrestricted dependency installation **Risk Level**: Medium ### Vulnerable Code ```markdown ### "Command not found" errors Ensure you have Python 3 and required packages installed: ```bash pip3 install requests beautifulsoup4 ``` ``` The installation script repeats the unsafe recommendation at `scripts/install.sh:18-21`: ```bash if ! python3 -c "import requests, bs4" 2>/dev/null; then echo "Warning: Required Python packages (requests, beautifulsoup4) not found." echo "You may need to install them with: pip install requests beautifulsoup4" fi ``` ### Technical Analysis The project instructs users to install `requests` and `beautifulsoup4` without version constraints or integrity hashes. As a result, the installed dependency versions depend on the current state of the configured Python package index. Although both package names appear legitimate, the installation process does not guarantee that users receive versions reviewed by the project author. It is also affected by custom or compromised package indexes, dependency compromise, and malicious future releases. Python packages may execute arbitrary code during installation or when imported by the Skill. ### Attack Path 1. An attacker compromises a referenced package release, one of its transitive dependencies, or a package index configured on the victim's system. 2. The user follows the documented command: `pip3 install requests beautifulsoup4`. 3. Pip resolves and downloads an unreviewed package version from the configured index. 4. Malicious installation or import-time code executes under the account running pip or the Skill. 5. The malicious dependency can access resources available to that account and can alter the Skill's behavior. This path requires compromise or manipulation of the dependency supply chain; the audited project does not itself host or retrieve a known malicious package. ### ...[truncated 393 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Add a reviewed dependency lock or requirements file with exact versions: ```text requests==<reviewed-version> beautifulsoup4==<reviewed-version> ``` 2. Generate and verify cryptographic hashes, then install with: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` 3. Pin all transitive dependencies where reproducible builds are required. 4. Recommend installation inside a dedicated virtual environment rather than the system Python environment. 5. Periodically scan pinned dependencies for known vulnerabilities and update them through a controlled review process. 6. Update both `README.md` and `scripts/install.sh` so they reference the secured requirements file instead of unconstrained package names. ]]>
