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. 14 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:** 4.5.137 - **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. Source inspection found no install-time execution or malicious behavior. The flagged agent-configuration location only classifies paths for git filtering, and the CLI telemetry sends limited product-use metadata with an opt-out. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-18T14:45:34.468Z - **Finished:** 2026-10-18T14:46:41.264Z - **Download time:** 763 ms - **Static scan time:** 4106 ms - **AI review time:** 61926 ms - **Total time:** 66796 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 malicious attack surface was identified. The inspected automatic network behavior is limited to command telemetry sent to the MMI Hub. - **Trigger:** Telemetry runs when a user invokes an mmi-cli command; the package manifest declares no install lifecycle hook. - **Impact:** This exposes limited command-use metadata to the configured Hub; the inspected telemetry payload contains no credentials or project files. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T14:46:41.264Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends the command path, version, CI status, and operating system to the Hub telemetry endpoint, with an environment-variable opt-out. - **Rationale:** Source inspection found no install-time execution or malicious behavior. The flagged agent-configuration location only classifies paths for git filtering, and the CLI telemetry sends limited product-use metadata with an opt-out. - **Files touched:** package.json, .codex-plugin/plugin.json, cli/dist/main.cjs - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com/telemetry/cli-call ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package manifest declares no lifecycle scripts and packages the plugin manifest, skills, launcher, and CLI files., The plugin manifest describes MMI workflow skills and guarded hooks as product capabilities., The flagged agent-directory code classifies paths for git change filtering; it does not modify agent configuration., When an mmi-cli command runs, telemetry sends its command path, version, CI status, and OS to the configured MMI Hub endpoint; MMI\_TELEMETRY=off disables this request., The telemetry uses the package’s default Hub endpoint unless MMI\_HUB\_URL is set. ## Affected versions and remediation This report applies to @mutmutco/codex-plugin@4.5.137. - Review the evidence and your use of @mutmutco/codex-plugin@4.5.137 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.
