Security Findings6
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Node.js child_process require Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/swancho/mac-reminders-agent/cli.js:8 | |

| CRITICAL | Arbitrary command execution Node.js synchronous shell execution Review all shell execution calls.

| MEDIUM | Unpinned dependency in package.json The `package.json` specifies the `applescript` dependency with a caret range (`^1.0.0`). This allows `npm` to install any `1.x.x` version, which introduces a supply chain risk. A future minor or patch release could potentially contain vulnerabilities or malicious code without explicit review, leading to unexpected behavior or security compromises. Pin the dependency to an exact version (e.g., `"applescript": "1.0.0"`) to ensure deterministic builds. If a `package-lock.json` is used, ensure it is committed and respected during installation. Regularly audit dependencies for known vulnerabilities. | LLM | package.json:10 |
