Vulnerability Type: Supply-chain exposure through unpinned and unverified Python dependencies
Risk Level: MediumVulnerable Code
markdown ## Dependencies Required packages: - `numpy` - Array operations - `qmt` - Quaternion utilities - `ahrs` - Quaternion class - `matplotlib` - 3D visualization Install with: ```bash pip install numpy qmt ahrs matplotlibtext ### Technical Analysis The documented installation command retrieves mutable versions of four third-party packages from the Python package index configured in the user's environment. No exact versions, cryptographic hashes, lockfile, or trusted index URL are specified. This makes installation non-reproducible and prevents users from verifying that installed artifacts match versions reviewed by the project author. If a package release or configured package index is compromised, pip may download attacker-controlled content. Source distributions can invoke build backends during installation, while malicious package code can execute when imported or used. The project contains only `SKILL.md`; it does not include the implementation of `pywayne.vio.tools` or dependency metadata that would allow the documented code and its dependency graph to be audited or reproduced. ### Attack Path 1. A user follows the documented command: ```bash pip install numpy qmt ahrs matplotlib- Pip resolves the latest compatible packages using the environment's configured index and dependency resolver.
- An attacker compromises a referenced package release, one of its transitive dependencies, or an untrusted package index configured on the system.
- Pip downloads and installs the attacker-controlled distribution because no approved versions or hashes are enforced.
- Malicious behavior executes through package build logic, or later when the dependency is imported by the documented VIO workflow.

Remediation Suggestions
- Pin every direct dependency to a reviewed version rather than allowing unconstrained resolution.
- Generate a lock or requirements file containing all direct and transitive dependencies.
- Record cryptographic hashes for every permitted distribution and enforce them:
bash python -m pip install --require-hashes -r requirements.txt - Prefer a controlled internal mirror or explicitly document and enforce the trusted package index.
- Review new dependency versions before updating pins, and automate vulnerability and provenance scanning in CI.
- Install dependencies inside an isolated virtual environment or container under a non-privileged account.
- Include the source implementation of
pywayne.vio.tools, or provide a verifiable source and release reference, so users can confirm that the imported module corresponds to the audited implementation. - Avoid privileged pip installation and disable unnecessary access to secrets and production resources during dependency installation.
