Vulnerability Details
File Location:
scripts/README.md, lines 27–28, 34, 37, and 40
Vulnerability Type: Insecure third-party dependency installation
Risk Level: MediumThe documented installation process uses mutable, unpinned PyPI dependencies and instructs users to install
sqlite3andasyncio, even though both names correspond to modules included in Python's standard library.bash pip install playwright beautifulsoup4 requests pandas numpy playwright install chromiumbash # Data visualization pip install matplotlib seaborn # Database storage pip install sqlite3 pymongo # Asynchronous processing pip install aiohttp asyncioTechnical Analysis
None of the third-party dependencies are constrained to reviewed versions or verified with cryptographic hashes. Consequently, executing these commands installs whatever versions the configured package index resolves at that time. Future releases, compromised maintainer accounts, malicious dependency updates, or a compromised package index could therefore introduce code that was not part of the audited Skill.
The instructions to install
sqlite3andasyncioare particularly unsafe and unnecessary. These modules are supplied by supported Python versions and should not be retrieved from PyPI. A third-party distribution published under a standard-library module name is not required by this project and may contain unrelated or hostile code. This creates dependency-confusion and package-takeover exposure.Several other documented dependencies are not used by the included
scripts/jd_scraper.py, unnecessarily increasing the project's trusted computing base and supply-chain attack surface.Attack Path
- A user or automated Agent follows the dependency installation instructions in
scripts/README.md. pipqueries its configured package index and resolves the unpinned package names to their currently available distributions ...[truncated 1246 chars]

Remediation Suggestions
- Remove
sqlite3andasynciofrom all installation commands because they are Python standard-library modules. - Remove packages that are not required by the files actually shipped with the Skill. The included scraper directly requires only reviewed dependencies corresponding to its imports, such as
requestsandbeautifulsoup4. - Define dependencies in a dedicated requirements or project metadata file rather than informal shell commands.
- Pin every direct and transitive dependency to an explicitly reviewed version using a generated lock file.
- Record and enforce cryptographic hashes, for example:
bash python -m pip install --require-hashes -r requirements.txt - Separate optional dependencies into clearly identified extras so users do not install unrelated packages by default.
- Configure installations to use a trusted package index and consider an internally controlled dependency mirror for automated or production environments.
- Run dependency installation in an isolated virtual environment or container under a non-privileged account.
- Add automated dependency scanning and review dependency updates before regenerating the lock file.
- Document the supported Python version and verify that required standard-library modules are available without third-party installation.
- Remove
