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 lifecycle hooks in package.json and no confirmed attack behavior. The credential transfer is part of a Hub session exchange, and the flagged agent-configuration path is used during plugin repair. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-17T09:54:08.751Z - **Finished:** 2026-10-17T09:54:56.799Z - **Download time:** 1015 ms - **Static scan time:** 5696 ms - **AI review time:** 41336 ms - **Total time:** 48048 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 flagged token transfer is an authentication exchange with the package’s MMI Hub service. - **Trigger:** A user invokes the CLI command that needs a Hub session or runs the explicit plugin repair flow. - **Impact:** No concrete malicious effect was established from these behaviors. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T09:54:56.799Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends a GitHub token to the configured MMI Hub session endpoint; the marketplace repair flow reads and restores relevant settings around repair steps. - **Rationale:** Source inspection found no lifecycle hooks in package.json and no confirmed attack behavior. The credential transfer is part of a Hub session exchange, and the flagged agent-configuration path is used during plugin repair. - **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:** package.json declares the package identity and ships the CLI; it defines no lifecycle hooks., The CLI’s default Hub endpoint is package-aligned with the MMI Hub service., The CLI sends a GitHub token to that Hub’s session endpoint as an authentication exchange., The agent-integration location identifies Claude’s marketplace settings file; the heal flow reads its pins, runs plugin repair steps, then restores those pins., The launcher requires the sibling CLI bundle only when invoked; its version-only path prints the package version. ## Affected versions and remediation This report applies to @mutmutco/codex-plugin@4.5.174. - Review the evidence and your use of @mutmutco/codex-plugin@4.5.174 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.
