## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 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:** 0.0.189-prod.1790432436302.g20f5390e5f835d2747b0dd9125992cf5e47ec012
- **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.

The package is a user-invoked Chrome keeper: it has no npm lifecycle hook, launches Chrome only from the CLI path, and authenticates to an HTTPS origin that defaults to the product host. Remote page JavaScript and loopback forwards are browser-control features of that started client, not a hidden install-time attack.

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 install-time or import-time attack was identified. Browser launch, authenticated relay calls, page script execution, and loopback forwards run only after the user starts the r5d-browser CLI.

- **Trigger:** User runs the r5d-browser CLI, typically the start command.

- **Impact:** Effects stay within the user-started browser session and that HTTPS API. No unsolicited credential harvest, persistence, or foreign agent-config mutation was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-26T16:40:28.655Z

### AI review details

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

- **Mechanism:** The client launches local Chrome and posts the supplied bearer token to the configured HTTPS r5d origin for registration and polling.

- **Rationale:** The package is a user-invoked Chrome keeper: it has no npm lifecycle hook, launches Chrome only from the CLI path, and authenticates to an HTTPS origin that defaults to the product host. Remote page JavaScript and loopback forwards are browser-control features of that started client, not a hidden install-time attack.

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

### Review decision

- **Verdict:** Clean

- **Confidence:** 86.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json exposes only the user CLI bin r5d-browser and has no install lifecycle scripts or self-dependency., Chrome is started with spawn of a resolved local Chrome executable and explicit launch arguments when the keeper runs., run\_js is an explicit browser action that evaluates supplied page code through Playwright page.evaluate, not at install or import., The personal client accepts only an HTTPS origin, defaulting to https://r5d.dev, and sends the caller token to that origin.

- **Evidence against:** A remote poll can request browser actions, including page JavaScript and loopback port forwards, after the user starts the client., The bearer token and base URL can come from flags, environment, or the private r5d config rather than a hard-coded host allowlist.
