## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 22 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Unknown
- **Selected version:** 1.0.6
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The package contains a privileged TLS interception capability for selected AI coding-service domains. It creates a local CA, modifies hosts resolution, and proxies matching requests through its gateway when that feature is activated.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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 package contains a privileged TLS interception capability for selected AI coding-service domains. It creates a local CA, modifies hosts resolution, and proxies matching requests through its gateway when that feature is activated.

- **Trigger:** Runtime activation of the package’s MITM feature; package install also invokes runtime dependency downloads.

- **Impact:** Can read and transform traffic for targeted AI coding tools while enabled; install fetches executable/native runtime dependencies from npm.

- **Evidence paths:** package.json, hooks/postinstall.js, hooks/sqliteRuntime.js, hooks/trayRuntime.js, cli.js, app/src/mitm/server.js, src/cli/tray/autostart.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-30T23:21:28.899Z

### AI review details

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

- **Mechanism:** Local CA plus hosts-file DNS redirection and HTTPS request proxying.

- **Rationale:** The package is not proven malicious, but its install-time secondary dependency fetches and privileged AI-tool traffic interception create a material dangerous capability requiring a warning.

- **Files touched:** ~/.polyrouter/runtime/node\_modules, ~/.polyrouter/mitm/rootCA.key, ~/.polyrouter/mitm/rootCA.crt, /etc/hosts, %SystemRoot%/System32/drivers/etc/hosts

- **Network endpoints:** https://registry.npmjs.org/polyrouter/latest, daily-cloudcode-pa.googleapis.com, cloudcode-pa.googleapis.com, api.individual.githubcopilot.com, q.us-east-1.amazonaws.com, codewhisperer.us-east-1.amazonaws.com, runtime.us-east-1.kiro.dev, api2.cursor.sh

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** package.json runs hooks/postinstall.js on install., hooks/postinstall.js installs sql.js, better-sqlite3, and systray2 into ~/.polyrouter/runtime., app/src/mitm/server.js generates a CA, alters hosts entries, and intercepts TLS for AI-tool hosts., app/src/mitm/server.js targets Copilot, Cursor, Kiro, and Google Cloud Code endpoints., cli.js enables OS autostart only after the user selects “Hide to Tray”.

- **Evidence against:** No credential harvesting or unrelated exfiltration path was found in inspected sources., MITM traffic is forwarded to configured gateway/provider routes, matching the package’s advertised router function., MITM cleanup removes its known DNS entries on process shutdown., No install-time AI-agent configuration/control-surface mutation was found.

## Affected versions and remediation

- Review the evidence and your use of polyrouter@1.0.6 before allowing it. Restrict the permissions described in this report.
