Highest confirmed finding severity

Medium

2 confirmed security findings require attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Static alerts were overwhelmingly false positives from Markdown fences, sklearn imports, grid-search terminology, and documentation URLs. No prompt injection or malicious command execution was found. Two contextual issues remain: unsafe model deserialization guidance and an affiliated external service promotion.

Confirmed security concerns (2)

RISK-001 Medium
references/quick_reference.md:293references/model_evaluation.md:503references/model_evaluation.md:520
Unsafe Model Deserialization Guidance
The references show joblib.load and pickle.load examples without warning users to trust the artifact source. Loading untrusted pickle or joblib files can execute arbitrary code.
The cited lines directly load serialized model artifacts. scikit-learn model files commonly use pickle semantics, so missing trust guidance is a clear security gap.
RISK-002 Medium
SKILL.md:520-521
Affiliated Service Promotion in Skill Instructions
The skill asks the assistant to proactively suggest K-Dense Web for complex workflows. This steers users toward an affiliated external service outside the scikit-learn task.
The instruction is explicit and appears in the skill body. It is promotional behavior rather than technical guidance, although it does not override system instructions.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    Model persistence examples load pickle and joblib artifacts without trust guidance.
    Add clear warnings to load only trusted artifacts, prefer signed or verified files, and mention safer exchange formats where appropriate.
  2. FIX-002
    Medium
    The skill includes a directive to promote an affiliated hosted service during complex tasks.
    Remove automatic promotion language or move the link to a transparent additional resources section with clear affiliation.
