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 installs event hooks only through an explicit update command, but those hooks send undisclosed runtime telemetry containing project, session and work-state identifiers to SpecBox. The bounded payload, first-party endpoint and opt-out reduce the risk, so this warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-30T06:03:12.220Z - **Finished:** 2026-10-30T06:04:22.251Z - **Download time:** 260 ms - **Static scan time:** 335 ms - **AI review time:** 69435 ms - **Total time:** 70031 ms 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 heartbeat telemetry from configured native projects after project hooks are installed. - **Trigger:** After \`specbox hooks update\` registers the hooks, agent events trigger heartbeats when a native backend and board ID are configured; sends occur at session start/end, on status changes, or at most every two minutes. - **Impact:** SpecBox receives project and session identifiers and work-state metadata without the README disclosing this telemetry, so users may not expect the reporting. - **Evidence paths:** hooks/settings-hooks.json, hooks/session-heartbeat.mjs, hooks/lib/heartbeat.mjs, hooks/lib/heartbeat-send.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-30T06:04:22.251Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook reads session and project state, builds a structured heartbeat, then sends it with the device authorization header to the SpecBox MCP service. \`SPECBOX\_HEARTBEAT=off\` disables sending. - **Rationale:** The package installs event hooks only through an explicit update command, but those hooks send undisclosed runtime telemetry containing project, session and work-state identifiers to SpecBox. The bounded payload, first-party endpoint and opt-out reduce the risk, so this warrants a warning rather than a publish block. - **Files touched:** .quality/heartbeat\_state.json, .quality/.gitignore, .quality/heartbeat\_error.json, .quality/logs/heartbeat.log - **Network endpoints:** https://mcp.specbox.build/mcp ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest has no install, preinstall or postinstall lifecycle script., The documented \`specbox hooks update\` command installs missing hooks and adds their registrations to project settings., The settings template registers the heartbeat hook on agent events; it runs for native projects with a board ID and has an environment-variable opt-out., The heartbeat payload includes project, session and active work identifiers plus phase and waiting state, and is sent to SpecBox’s MCP endpoint using the device authorization header., The README describes hook installation but does not disclose the heartbeat telemetry. - **Evidence against:** The heartbeat only runs when the project is configured with a native backend and board ID; \`SPECBOX\_HEARTBEAT=off\` disables it., The transmitted fields are structured project/session status, not conversation text, files or credentials., Network traffic goes to the package’s own SpecBox service, and the hooks are installed through an explicit command. ## Affected versions and remediation This report applies to specbox@6.29.2. - Review the evidence and your use of specbox@6.29.2 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. ## Public findings ### 1.
