Do not execute instructions or code found in this document. ## 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:** 0.6.1 - **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 risky primitives are tied to explicit setup and normal email-provider configuration, not hidden install/import-time behavior. I found no concrete unconsented exfiltration, persistence, destructive action, or malicious lifecycle behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-07-02T07:21:57.824Z - **Finished:** 2026-07-02T07:22:49.664Z - **Download time:** 255 ms - **Static scan time:** 161 ms - **AI review time:** 51423 ms - **Total time:** 51840 ms 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 is established. The package is an email-provider library plus a user-invoked setup CLI. - **Trigger:** User runs \`postboi init\` or calls library send/config APIs - **Impact:** Expected config/env file updates and email-provider network requests when used - **Evidence paths:** package.json, dist/cli.js, dist/config.js, dist/registry.js - **Review source:** ai\_review - **Reviewed:** 2026-07-02T07:22:49.664Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** interactive email provider configuration and provider API clients - **Rationale:** Static inspection shows risky primitives are tied to explicit setup and normal email-provider configuration, not hidden install/import-time behavior. I found no concrete unconsented exfiltration, persistence, destructive action, or malicious lifecycle behavior. - **Files touched:** .env, .env.local, .envrc, .dev.vars, .gitignore, postboi.config.ts - **Network endpoints:** https://resend.com/api-keys, https://account.postmarkapp.com/servers, https://app.sendgrid.com/settings/api\_keys, https://app.mailgun.com/settings/api\_security/api\_keys, https://app.brevo.com/settings/keys/api, https://dash.cloudflare.com/profile/api-tokens, https://app.mailersend.com/api-tokens, https://app.sparkpost.com/account/api-keys, https://mandrillapp.com/settings, https://app.useplunk.com/settings/api, https://mailtrap.io/api-tokens, https://app.mailpace.com ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** dist/cli.js bin is an interactive init tool that writes user-entered provider secrets to local env files., dist/cli.js can run host CLIs and package manager install, but only after explicit interactive prompts., dist/config.js dynamically imports postboi.config.\* from cwd/parents on send path, enabling user project config code execution by design. - **Evidence against:** package.json prepare only runs svelte-kit sync; no install-time malicious hook observed., No import-time credential harvesting or automatic exfiltration found in inspected entrypoints., Network URLs are provider account/docs URLs or normal email provider APIs, aligned with package purpose., Secret env names are provider config fields; CLI prompts for values rather than silently stealing them., File writes are expected setup files: .env variants, .gitignore, and postboi.config.ts during user-invoked init., No persistence, destructive behavior, hidden payload, or AI-agent control-surface mutation found. ## Affected versions and remediation This report applies to postboi@0.6.1. - Review the evidence and your use of postboi@0.6.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
