- Unpinned Third-Party Runtime Dependencies## Vulnerability Details **File Location**: `SKILL.md`, lines 31–34 and 40 **Vulnerability Type**: Unpinned third-party dependencies **Risk Level**: Medium ### Vulnerable Code Snippet ```markdown - `httpx` — HTTP client (`pip3 install httpx`) - `lxml` — HTML parser (`pip3 install lxml`, pre-installed on macOS) - (Optional) `socksio` — for SOCKS proxy support (`pip3 install socksio`) - (Optional) `pyyaml` — for config parsing (`pip3 install pyyaml`; falls back to built-in parser) ``` ```bash pip3 install httpx lxml ``` ### Technical Analysis The installation instructions resolve mutable latest versions of packages from the configured Python package index. No reviewed versions, integrity hashes, or lock file are provided. This creates a supply-chain exposure: a compromised package release, compromised transitive dependency, malicious package-index configuration, or unsafe future update could introduce arbitrary code during installation or runtime. The audit did not identify a currently malicious dependency; the issue is the absence of reproducible and integrity-verified dependency resolution. ### Attack Path 1. An attacker compromises a listed package, one of its transitive dependencies, or the package source configured on the victim's system. 2. A user follows the documented `pip3 install httpx lxml` command. 3. `pip` resolves and downloads the mutable package version without checking a project-provided expected hash. 4. Malicious installation or imported runtime code executes with the privileges of the user running `pip` or the Skill. 5. That code can access resources available to the process, potentially including submitted search queries, proxy configuration, environment data, and user-accessible files. ### Impact Assessment Successful exploitation could result in arbitrary code execution under the installing or executing user's account. The resulting scope would be limited by that account's operating-system permissions, but could include theft or m ...[truncated 321 chars]
- Remediation
- ## Remediation Suggestions 1. Create a dependency lock file containing reviewed, exact versions for all direct and transitive dependencies. 2. Include cryptographic hashes and require their verification during installation, for example: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` 3. Install dependencies in a dedicated virtual environment rather than the system Python environment: ```bash python3 -m venv .venv . .venv/bin/activate python3 -m pip install --require-hashes -r requirements.txt ``` 4. Review dependency updates before changing locked versions and use automated vulnerability and provenance checks. 5. Document the trusted package index and discourage installation from unverified mirrors. 6. Pin optional dependencies such as `socksio` and `pyyaml` under the same integrity policy.
