Vulnerability Details
File Location:
SKILL.md:89
Vulnerability Type: Unpinned third-party dependencies and missing integrity verification
Risk Level: MediumVulnerable Code Snippet:
bash pip install httpx aiohttp beautifulsoup4 lxml requestsTechnical Analysis
The installation instruction retrieves five third-party packages without specifying reviewed versions or cryptographic hashes. Dependency resolution therefore varies over time and trusts whichever distributions the configured Python package index supplies when the command is executed.
Python packages can run package-controlled build or installation logic. If a dependency release or the configured package index is compromised, following this instruction could cause unreviewed code to execute with the privileges of the user running
pip. The absence of a lock file and hash verification also prevents reproducible installation and makes unexpected dependency changes harder to detect.The audited package contains only
SKILL.md; it does not include the referencedmain.pyimplementation. Therefore, the dependency set cannot be validated against an actual implementation, and the necessity and safe version ranges of these packages cannot be established from the available project contents.Attack Path
- An attacker compromises a listed package, one of its transitive dependencies, or a package index used by the victim.
- The attacker publishes a malicious release that satisfies unrestricted dependency resolution.
- A user follows the documented
pip installcommand. pipresolves and downloads the attacker-controlled distribution because no version or hash constraints are present.- Malicious build, installation, or runtime code executes in the user's environment.
- The resulting access is limited by the privileges and environment of the user running the installation or subsequently importing the package.

Remediation Suggestions
- Pin every direct dependency to a reviewed version and constrain transitive dependencies through a generated lock file.
- Record cryptographic hashes for all resolved distributions and install them with hash enforcement, such as
pip install --require-hashes -r requirements.txt. - Generate and review the lock file using a dependency-management tool such as
pip-tools, Poetry, or uv. - Install dependencies inside an isolated virtual environment under a non-privileged account; do not run
pipwith administrator or root privileges. - Configure an approved package index and disable untrusted supplemental indexes to reduce dependency-confusion exposure.
- Add automated dependency vulnerability and integrity scanning to the release process.
- Include the referenced implementation in the package so reviewers can verify which dependencies are genuinely required and remove unused packages.
