Trust Assessment
portable-email-manager received a trust score of 60/100, placing it in the Caution category. This skill has some security considerations that users should review before deployment.
SkillShield's automated analysis identified 3 findings: 1 critical, 0 high, 1 medium, and 1 low severity. Key findings include Unpinned npm dependency version, Node lockfile missing, Insecure IMAP connection: TLS certificate validation disabled.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. All layers scored 70 or above, reflecting consistent security practices.
Last analyzed on February 13, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings3
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Insecure IMAP connection: TLS certificate validation disabled The IMAP configuration explicitly sets `tlsOptions: { rejectUnauthorized: false }`. This disables TLS certificate validation, making the connection vulnerable to Man-in-the-Middle (MITM) attacks. An attacker could intercept the connection, impersonate the IMAP server, and harvest the `EMAIL_USER` and `EMAIL_PASS` credentials, as well as read or modify email content. Remove or set `rejectUnauthorized` to `true` in `tlsOptions` to ensure proper TLS certificate validation. For production use with public email providers, `rejectUnauthorized: true` (or omitting the option, as `true` is often the default) is essential. | LLM | scripts/email.js:46 | |
| MEDIUM | Unpinned npm dependency version Dependency 'imap-simple' is not pinned to an exact version ('^5.1.0'). Pin dependencies to exact versions to reduce drift and supply-chain risk. | Dependencies | skills/jorgermp/email-manager-lite/package.json | |
| LOW | Node lockfile missing package.json is present but no lockfile was found (package-lock.json, pnpm-lock.yaml, or yarn.lock). Commit a lockfile for deterministic dependency resolution. | Dependencies | skills/jorgermp/email-manager-lite/package.json |
