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 Dependency Installation The skill instructs users to install `pydeseq2` without specifying a version. This can lead to supply chain risks where a new, potentially vulnerable version of the package or its transitive dependencies could be installed, introducing security flaws or breaking changes. It's best practice to pin dependencies to specific versions to ensure reproducibility and security. Pin the dependency to a specific, known-good version. For example, `uv pip install pydeseq2==X.Y.Z` where X.Y.Z is a tested version. Regularly review and update pinned versions.	Static	SKILL.md:403
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
