Vulnerability Details
File Location:
SKILL.md:147and repeated atSKILL.md:333-335
Vulnerability Type: Supply-chain risk caused by unpinned dependencies
Risk Level: Mediumbash pip install requests beautifulsoup4 markdownThe dependency table repeats the same installation pattern:
bash pip install requests pip install beautifulsoup4 pip install markdownTechnical Analysis
The installation instructions do not pin package versions or require verified artifact hashes. Consequently, each installation resolves whatever package versions the configured Python package index currently considers suitable.
This makes the installed environment non-reproducible and exposes users to upstream supply-chain events. If a listed package, one of its transitive dependencies, the selected package index, or the user's package-index configuration is compromised, following these instructions could install attacker-controlled code.
Python packages may execute build-system or installation-related code during installation. Malicious package code can also execute later when the installed module is imported. The audit did not establish that the currently published packages are malicious; the confirmed weakness is that the skill provides no version or integrity controls against future or index-dependent changes.
Attack Path
- An attacker compromises a listed package, one of its transitive dependencies, or a package index used by the target environment.
- The attacker publishes a malicious release that remains compatible with the unconstrained package requirement.
- A user follows the skill's documented
pip installcommand. pipresolves and downloads the attacker-controlled release because no approved version or artifact hash is specified.- Malicious code executes during package installation, package build processing, or a subsequent import.

Remediation Suggestions
- Replace unconstrained package names with reviewed, exact versions, for example:
text requests==<reviewed-version> beautifulsoup4==<reviewed-version> markdown==<reviewed-version> - Maintain dependencies in a lock file generated by a tool such as
pip-tools, Poetry, or another reproducible dependency manager. - Require artifact hashes by installing with a hash-locked requirements file:
bash python -m pip install --require-hashes -r requirements.txt - Pin and review transitive dependencies, not only the three direct dependencies.
- Install inside an isolated virtual environment rather than the system Python environment, and do not use administrator or root privileges.
- Use only an explicitly configured, trusted package index over HTTPS. Prevent unintended fallback to untrusted extra indexes.
- Add automated dependency auditing and controlled update review. Regenerate locks and hashes only after validating new releases.
- Update all repeated installation examples at
SKILL.md:333-335so they do not encourage bypassing the locked installation process.
