# specbox@6.30.0 npm security report

## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 13 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:** 6.30.0
- **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 no install-time hook, and heartbeat reporting is limited to projects configured for SpecBox's native board. However, installed hooks automatically send project and session identifiers and work state to the service without a clear user-facing disclosure, so this is suspicious telemetry.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-30T06:04:29.704Z

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:** Undisclosed runtime telemetry shares project and session state with SpecBox; no broader attack was identified.

- **Trigger:** After a user runs specbox hooks update, registered hooks send heartbeat data on session start and user prompt events in eligible projects.

- **Impact:** SpecBox receives identifiable project and work-session status without the README explaining this data flow; the hook can be disabled with SPECBOX\_HEARTBEAT=off.

- **Evidence paths:** hooks/settings-hooks.json, hooks/session-heartbeat.mjs, hooks/lib/heartbeat.mjs, hooks/lib/heartbeat-send.mjs, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-10-30T06:05:16.718Z

### AI review details

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

- **Mechanism:** The hook reads the project board ID and session context, then sends project\_id, session\_id, UC, phase, and waiting state to the SpecBox MCP heartbeat tool using the device authorization helper.

- **Rationale:** The package has no install-time hook, and heartbeat reporting is limited to projects configured for SpecBox's native board. However, installed hooks automatically send project and session identifiers and work state to the service without a clear user-facing disclosure, so this is suspicious telemetry.

- **Files touched:** .claude/hooks/session-heartbeat.mjs, .quality/heartbeat\_state.json, .quality/.gitignore

- **Network endpoints:** https://mcp.specbox.build/mcp

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The hook configuration registers session-heartbeat on session start and user prompt events., Heartbeat payloads include project\_id, session\_id, UC identifier, phase, and waiting state., The hook sends the payload to report\_session\_heartbeat at mcp.specbox.build using the device authorization helper., README documents the hooks update command but does not explain the heartbeat data it sends.

- **Evidence against:** The heartbeat runs only when the project is configured with a native backend and board ID., Project hook files and registrations are written only by the explicit specbox hooks update command., The destination is SpecBox's own MCP service, and SPECBOX\_HEARTBEAT=off disables the heartbeat., package.json declares no install, preinstall, or postinstall lifecycle script.
