Security Findings3

Severity	Finding	Layer	Location
MEDIUM	Sensitive environment variable access: $USER Access to sensitive environment variable '$USER' detected in shell context. Verify this environment variable access is necessary and the value is not exfiltrated.	Static	skills/youtube-summarizer/SKILL.md:108
MEDIUM	Unpinned Dependency in Installation Script The skill installs the 'youtube-transcript-api' Python package without specifying a version. This introduces a supply chain risk, as a future malicious update to the package or a typosquatting attack could lead to the installation of compromised code. It is best practice to pin dependencies to a specific version or a version range to ensure reproducibility and security. Pin the dependency to a specific version. For example, `pip3 install youtube-transcript-api==X.Y.Z` or `pip3 install 'youtube-transcript-api<A.B.C,>=X.Y.Z'`.	LLM	scripts/install-dependencies.sh:7
MEDIUM	Unpinned Dependency Mentioned in SKILL.md The skill's documentation and setup instructions mention installing 'youtube-transcript-api' without specifying a version. This reinforces the supply chain risk identified in the installation script, as users might manually install it unpinned or the automated installation process will use the latest available version, which could be compromised. Update the documentation and installation instructions to recommend or enforce pinning the dependency to a specific, known-good version. For example, `pip install youtube-transcript-api==X.Y.Z`.
