## 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:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Staged Payload Carrier
- **Selected version:** 0.3.0
- **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 has an install-time native payload download and high-privilege runtime features, warranting a warning. Fixed checksum verification, package-owned storage, and no confirmed exfiltration or foreign control-surface mutation do not meet the blocking threshold.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 91.0%

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:** Installation fetches two executable native helpers into Negotium's state directory. Later user-driven runtime features spawn those helpers and can launch agent sessions with broad permissions.

- **Trigger:** npm postinstall downloads the helpers; later Negotium browser/background-bash or agent runtime use activates them.

- **Impact:** Supply-chain and high-privilege agent-runtime risk; no confirmed malicious exfiltration or install-time execution.

- **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/background-bash.js, dist/browser-runtime.js, dist/main.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T22:06:02.937Z

### AI review details

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

- **Mechanism:** verified native-binary bootstrap plus user-invoked agent and shell execution

- **Rationale:** The package has an install-time native payload download and high-privilege runtime features, warranting a warning. Fixed checksum verification, package-owned storage, and no confirmed exfiltration or foreign control-surface mutation do not meet the blocking threshold.

- **Files touched:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, ~/.negotium/binaries/browser-rs/v0.1.19/browser-rs, ~/.negotium/binaries/bash-rs/v0.1.5/bash-rs, dist/background-bash.js, dist/browser-runtime.js, dist/main.js

- **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/v0.1.19, https://github.com/maestrojeong/bash-rs-mcp/releases/download/v0.1.5

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** package.json postinstall invokes both installer scripts., install-browser-rs.mjs downloads a native executable to ~/.negotium/binaries and chmods it executable., install-bash-rs.mjs likewise installs an executable native payload., dist/background-bash.js later spawns the installed bash-rs binary., dist/main.js runs agent sessions with broad permission settings.

- **Evidence against:** Both installer downloads use fixed GitHub release URLs and pinned SHA-256 checksums., Installers do not execute the downloaded binaries during postinstall., Installers only write the package-owned ~/.negotium state directory., No source-confirmed credential exfiltration or foreign agent-config mutation was found.

## Affected versions and remediation

This report applies to negotium@0.3.0.

- Review the evidence and your use of negotium@0.3.0 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.
