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:** 4.5.175 - **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 install lifecycle hook. The inspected network requests are limited to MMI Hub telemetry and a Hub authentication exchange, while marketplace configuration changes occur only during explicit repair and preserve existing pins. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-17T16:34:12.731Z - **Finished:** 2026-10-17T16:35:47.626Z - **Download time:** 1811 ms - **Static scan time:** 5734 ms - **AI review time:** 87349 ms - **Total time:** 94895 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. The CLI sends limited command telemetry and exchanges GitHub authentication for an MMI Hub session. - **Trigger:** Telemetry runs when a CLI command action begins; Hub authentication runs when a command requests a Hub session. Marketplace repair requires the explicit plugin-heal command. - **Impact:** No unauthorized credential transfer or unconsented agent configuration change was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T16:35:47.626Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Telemetry contains the command path, version, CI status, and operating system. Hub authentication posts the GitHub token to the Hub session endpoint; plugin repair preserves existing marketplace pins around reinstall. - **Rationale:** The manifest has no install lifecycle hook. The inspected network requests are limited to MMI Hub telemetry and a Hub authentication exchange, while marketplace configuration changes occur only during explicit repair and preserve existing pins. - **Files touched:** ~/.claude/plugins/known\_marketplaces.json - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest identifies the MMI Hub project and defines no install lifecycle hook., The Claude marketplace metadata path is used by an explicit plugin repair command, which preserves existing MMI and Jervaise marketplace pins across reinstall., CLI telemetry sends the invoked command path, client version, CI status, and operating system to the default Hub endpoint; setting MMI\_TELEMETRY to off disables it., Hub authentication exchanges a GitHub token for a Hub session at the Hub session endpoint; the default Hub URL belongs to the declared MMI product. ## Affected versions and remediation This report applies to @mutmutco/codex-plugin@4.5.175. - Review the evidence and your use of @mutmutco/codex-plugin@4.5.175 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.
