AI Security Review
scanned 4mo ago · by lpm-firewall-aiStatic 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.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Importing providers or running `postboi init`; package install does not run bundled CLI code.
Impact
No unconsented credential exfiltration or execution identified.
Mechanism
user-directed email provider setup and send operations
AI 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.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
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.
