Security Findings3

Severity	Finding	Layer	Location
MEDIUM	Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains.	Manifest	cli-tool/components/mcps/devtools/figma-dev-mode.json:4
MEDIUM	Unpinned Python Dependencies The skill's documentation in `SKILL.md` recommends installing Python dependencies without specifying exact versions (e.g., `pip install pdfplumber pypdf ...`). This practice introduces supply chain risks, as a future malicious or vulnerable version of a dependency could be installed automatically. It also makes builds non-deterministic, potentially leading to unexpected behavior or compatibility issues. Pin all dependencies to exact versions (e.g., `pdfplumber==0.7.0`) in a `requirements.txt` file. Instruct users to install dependencies using `pip install -r requirements.txt`. Regularly audit and update pinned versions to benefit from security patches while maintaining control over the installed versions.	LLM	SKILL.md:235
LOW	Covert behavior / concealment directives Multiple zero-width characters (stealth text) Remove hidden instructions, zero-width characters, and bidirectional overrides. Skill instructions should be fully visible and transparent to users.	Manifest	cli-tool/components/mcps/devtools/jfrog.json:4
