SKILL.md, line 136
Vulnerability Type: Unpinned third-party dependencies installed from an implicitly selected package index
Risk Level: MediumVulnerable Code:
bash # Dependency installation pip install aiohttp cryptographyTechnical Analysis
The documented installation command resolves
aiohttp,cryptography, and their transitive dependencies without fixed versions or package-integrity hashes. Consequently, installations are not reproducible, and the code installed during a future Skill invocation may differ from the code available when the Skill was audited.The command also relies on pip's configured package index without documenting or enforcing an approved source. If a dependency release, transitive dependency, package index, or local pip index configuration is compromised, an attacker-controlled package could be selected and installed. Python packages can execute code during installation or when subsequently imported.
There is no evidence in the audited project that the currently named packages are malicious. The vulnerability is the unsafe and mutable dependency-resolution process.
Attack Path
- An attacker compromises a future release or transitive dependency of a named package, or influences the package index used by pip.
- A user or Agent follows the instructions in
SKILL.mdand runspip install aiohttp cryptography. - Pip resolves the unpinned dependency to the attacker-controlled or compromised release because no reviewed version or integrity hash is enforced.
- Malicious package code executes during installation or when the package is imported by the intended application.
- The payload operates with the permissions and environmental access of the account running pip or the application.
Impact Assessment
Successful exploitation could provide arbitrary code execution with the privileges of the installing user. Depe ...[truncated 619 chars]

Remediation Suggestions
- Move direct and transitive dependencies into a reviewed lock file with exact versions.
- Generate and enforce cryptographic hashes for every resolved distribution, for example:
bash python3 -m pip install --require-hashes -r requirements.txt - Use a trusted, explicitly configured package index or an internally controlled package mirror rather than relying on ambient pip configuration.
- Review packages before updating the lock file and use automated dependency and vulnerability scanning.
- Install dependencies in an isolated virtual environment under a non-privileged account.
- Avoid
sudo pip installand other elevated installation methods. - Document a controlled dependency-update process so new releases are reviewed before deployment.
