Vulnerability Type: Unpinned third-party dependencies and non-reproducible installation
Risk Level: MediumVulnerable Code
text numpy sentence-transformers mcp[cli]The documented installation command in
SKILL.md, lines 20–24, installs these unconstrained dependencies:bash python -m pip install -r requirements.txtTechnical Analysis
None of the direct dependencies has an exact version constraint or integrity hash. Each installation can consequently resolve a different set of direct and transitive package versions.
This does not prove that any current dependency is malicious. However, it prevents reproducible security review and exposes users to upstream package compromise, malicious or defective future releases, and unexpected transitive dependency changes. Python package installation may execute package build logic with the privileges of the user performing the installation.
The dependencies use recognizable package names and the default Python package index; no evidence of typosquatting, dependency confusion through a private package name, or an explicitly unsafe package source was found. The risk arises from unconstrained resolution and absent integrity verification.
Attack Path
- An attacker compromises a direct or transitive dependency release, its maintainer account, or its distribution channel.
- A user follows the documented
pip installcommand. - The package resolver selects the affected release because no reviewed version is pinned.
- Malicious build, installation, import-time, or runtime code executes in the installation environment.
- The payload operates with the permissions available to the installing user or service account.
This path depends on an upstream supply-chain compromise; the audited repository itself does not retrieve or execute a custom remote payload.

Remediation Suggestions
-
Pin every direct dependency to a reviewed exact version using
==. -
Generate and commit a lock file containing resolved transitive dependencies.
-
Add cryptographic hashes and install with hash verification, for example:
bash python -m pip install --require-hashes -r requirements.lock -
Build lock files in a controlled environment using a tool such as
pip-tools, Poetry, or uv. -
Use automated dependency vulnerability and provenance scanning in CI.
-
Review dependency updates before regenerating the lock file.
-
Prefer isolated virtual environments or containers and avoid installing with root or administrator privileges.
-
For high-assurance deployments, obtain packages from an allowlisted internal mirror and verify model artifacts separately.
