## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 11 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.7.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Static inspection shows a legitimate email library with an interactive setup CLI; the suspicious filesystem, child\_process, dynamic import, env, and network usage are package-aligned and user-triggered. No install/import-time malicious behavior or unconsented data exfiltration was found.

## Latest scan

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. Risky primitives are aligned with an email-sending library and setup CLI: env/config writes, provider API requests, and optional deployment CLI secret pushes are user-invoked.

- **Trigger:** Importing providers or running \`postboi init\`; package install does not run bundled CLI code.

- **Impact:** No unconsented credential exfiltration or execution identified.

- **Evidence paths:** package.json, dist/cli.js, dist/env.js, dist/config.js, dist/cloud.js, dist/index.js, dist/resend.js, dist/postmark.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-02T12:48:46.708Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** user-directed email provider setup and send operations

- **Rationale:** Static inspection shows a legitimate email library with an interactive setup CLI; the suspicious filesystem, child\_process, dynamic import, env, and network usage are package-aligned and user-triggered. No install/import-time malicious behavior or unconsented data exfiltration was found.

- **Files touched:** .env, .env.local, .envrc, .dev.vars, .gitignore, postboi.config.ts

- **Network endpoints:** https://postboi.email/api/cli/start, https://postboi.email/api/cli/poll, https://postboi.email/v1/send, https://api.resend.com/emails, https://api.postmarkapp.com/email, https://api.sendgrid.com, https://api.mailgun.net

### Review decision

- **Verdict:** Clean

- **Confidence:** 90.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** dist/cli.js can write user-selected env files and .gitignore during explicit \`postboi init\`., dist/cli.js can spawn host/package-manager CLIs after interactive confirmation., dist/config.js dynamically imports local postboi.config.\* files on send path.

- **Evidence against:** package.json prepare only runs \`svelte-kit sync || echo ''\`; no install-time package code execution found., dist/cli.js actions are gated behind explicit \`postboi init\` and interactive prompts., dist/cli.js device auth calls postboi.email CLI endpoints for documented cloud login., dist/\* provider network calls target email provider APIs and send user-supplied mail payloads., dist/env.js only reads .env/.env.local as local configuration fallback; no exfiltration code found., No persistence, destructive behavior, credential harvesting, reviewer prompt manipulation, or AI-agent control writes found.
