Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 15 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:** 4.5.172 - **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 manifest has no npm lifecycle hooks, and the required marketplace location participates in reading marketplace status rather than changing agent settings. The inspected network behavior is limited to package-aligned CLI usage telemetry, so no confirmed attack surface remains. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-17T07:46:07.298Z - **Finished:** 2026-10-17T07:46:57.942Z - **Download time:** 1294 ms - **Static scan time:** 5638 ms - **AI review time:** 43712 ms - **Total time:** 50644 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:** No attack was identified in the inspected source. Running a CLI command sends limited usage telemetry to the configured Hub. - **Trigger:** A CLI command reaches its pre-action handler. - **Impact:** The Hub receives command usage metadata; the inspected payload does not include credentials or file contents. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T07:46:57.942Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler sends the command name, version, CI status, and operating system to the Hub telemetry endpoint; telemetry can be disabled through MMI\_TELEMETRY. - **Rationale:** The manifest has no npm lifecycle hooks, and the required marketplace location participates in reading marketplace status rather than changing agent settings. The inspected network behavior is limited to package-aligned CLI usage telemetry, so no confirmed attack surface remains. - **Files touched:** package.json, cli/dist/main.cjs - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com/telemetry/cli-call ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json identifies the package and contains no npm lifecycle scripts., The flagged marketplace code reads known marketplace data and computes update status; it does not show a write to agent configuration., CLI telemetry is sent to the configured Hub and contains the command name, package version, CI status, and operating system. The command name is built from command hierarchy names. - **Evidence against:** The inspected telemetry payload contains no credential or file-content fields, and the code allows telemetry to be disabled with MMI\_TELEMETRY set to off. ## Affected versions and remediation This report applies to @mutmutco/claude-plugin@4.5.172. - Review the evidence and your use of @mutmutco/claude-plugin@4.5.172 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.
