Vulnerability Type: Unpinned third-party dependencies and missing package integrity verification
Risk Level: MediumComplete Code Snippet:
text osmnx ezdxfThe installation instruction appears at
SKILL.md:18:text pip install -r requirements.txtTechnical Analysis
The dependency declarations do not specify reviewed versions or cryptographic hashes. Consequently,
pip install -r requirements.txtresolves the packages—and their transitive dependencies—from the active Python package index at installation time.This makes the installed code mutable relative to the audited project. A future compromised or malicious release, compromised transitive dependency, unsafe package-index configuration, or unexpected incompatible update could be installed without changes to this repository. Python packages can execute build-system or installation-related code during installation, and imported dependencies execute with the privileges of the user running the Skill.
The audit did not establish that the currently named packages are malicious. The finding concerns the absence of controls that make dependency resolution reproducible and integrity-verifiable.
Attack Path
- An attacker compromises a future release of a declared dependency or one of its transitive dependencies, or influences the package index used by the installer.
- A user follows the documented setup instruction:
bash pip install -r requirements.txt pipresolves the mutable, unpinned dependency set from the configured index.- The compromised package is downloaded and installed without hash validation.
- Malicious installation or runtime code executes under the installing or invoking user's account when installation occurs or when
grab_map.pyimports and uses the affected package.

Remediation Suggestions
- Pin each direct dependency to a reviewed, exact version:
text osmnx==<reviewed-version> ezdxf==<reviewed-version> - Generate and commit a lock file containing reviewed transitive dependency versions.
- Record cryptographic hashes and install with hash enforcement, for example:
bash python -m pip install --require-hashes -r requirements.txt - Generate hashes only after obtaining packages from a trusted index and reviewing the resolved dependency set.
- Use a dedicated virtual environment and run installation and map generation as a least-privileged user.
- Add automated dependency vulnerability and provenance scanning to the release process.
- Periodically update pinned versions through a controlled review process rather than allowing implicit upgrades at installation time.
