## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 0.0.193-prod.1790873622670.g6b118c2809e58c7652f8239d5a6a0e46c09ed82c
- **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.

Source proves conditional forwarding of existing service credentials to an unrestricted operator-selected HTTPS origin. This warrants a credential exposure warning, not a malware publication block.

## Security analysis

### Published attack-surface review

- **Summary:** An operator-selected HTTPS origin can receive an existing r5d credential. This establishes conditional credential exposure, but no confirmed malicious attack.

- **Trigger:** Run the start command with a custom base URL while an existing r5d credential is available.

- **Impact:** A custom server could receive a credential intended for another r5d environment.

- **Evidence paths:** dist/mjs/personal-main.mjs, dist/mjs/main.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-01T17:01:43.075Z

### AI review details

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

- **Mechanism:** Endpoint selection and credential fallback are independent; the registration request forwards the credential in its authorization header.

- **Rationale:** Source proves conditional forwarding of existing service credentials to an unrestricted operator-selected HTTPS origin. This warrants a credential exposure warning, not a malware publication block.

- **Network endpoints:** https://r5d.dev

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 92.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The connection accepts an operator-selected HTTPS origin without a service destination allowlist., Authentication can reuse existing r5d credentials from environment variables or local configuration independently of the selected origin., The request sends the selected token as a Bearer credential to the selected origin., The start command activates the personal browser connection and sends a registration request.

- **Evidence against:** No npm install lifecycle hooks or runtime self-dependency appear in package.json., Chrome launching and page JavaScript execution are consistent with the browser automation functionality., Requests reject redirects; no hidden unrelated recipient or concrete malware intent was established.
