Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 17 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 4.2.2 - **Selected version is latest:** Yes - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package has a targeted email setup path that automatically reports identifying user and project details to a hard-coded publisher address, without separate consent. This is suspicious runtime telemetry; the other flagged install and AI-provider flows appear tied to explicit project setup or user requests. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-31T13:51:06.627Z - **Finished:** 2026-10-31T13:51:44.124Z - **Download time:** 771 ms - **Static scan time:** 548 ms - **AI review time:** 36177 ms - **Total time:** 37497 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:** The email configuration command reports identifying setup details to a publisher-selected address when configuring an official-domain sender. - **Trigger:** The user runs the add-email setup command and configures a \`4brains.in\` sender. - **Impact:** The publisher receives identifying information about the user and project without a separate confirmation of the report. - **Evidence paths:** add-email.js, lib/codegen.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T13:51:44.124Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command automatically sends the sender address, provider, OS username, hostname, app name, and timestamp through the configured mail provider to \`pawan@4brains.in\`. - **Rationale:** The package has a targeted email setup path that automatically reports identifying user and project details to a hard-coded publisher address, without separate consent. This is suspicious runtime telemetry; the other flagged install and AI-provider flows appear tied to explicit project setup or user requests. - **Files touched:** .env, src/services/mailer.js - **Network endpoints:** api.sancharak.com, 4brains.in (pawan@4brains.in) ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The email setup command gathers the configured sender address, OS username, hostname, app name, provider, and timestamp for a notification., When an \`@4brains.in\` sender is configured, the package sends that notification to the hard-coded address \`pawan@4brains.in\`., The notification is sent automatically after setup, without asking the user to confirm the report., The package also hard-codes the shared authorization password for configuring that sender domain. - **Evidence against:** The notification is limited to configuring a \`4brains.in\` sender through the explicit \`add-email\` command., AI provider API keys are sent to their corresponding official provider endpoints when the user submits an AI plan request., The runtime npm install occurs during the explicit project scaffolding flow and installs the scaffold’s dependencies. ## Affected versions and remediation This report applies to 4bnode@4.2.2. - Review the evidence and your use of 4bnode@4.2.2 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.
