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 manifest has no lifecycle hook, and the flagged agent integration location is only part of a path classifier. However, Hub authentication forwards an existing GitHub token to an unrestricted MMI\_HUB\_URL override, leaving a concrete conditional credential exposure risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-18T13:22:54.721Z - **Finished:** 2026-10-18T13:24:08.679Z - **Download time:** 1288 ms - **Static scan time:** 3947 ms - **AI review time:** 68722 ms - **Total time:** 73958 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:** When a custom Hub URL is configured, an authenticated Hub request can send a GitHub token to that selected endpoint. The source does not establish misuse by the default Hub endpoint. - **Trigger:** A CLI operation requiring Hub authentication runs with MMI\_HUB\_URL set and no valid cached Hub session for that endpoint and token. - **Impact:** A custom endpoint can receive the GitHub token, exposing it to that endpoint’s operator. - **Evidence paths:** cli/dist/main.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-18T13:24:08.679Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI reads a GitHub token from environment variables or gh auth token and posts it as a bearer credential to the configured endpoint’s /auth/session route. - **Rationale:** The manifest has no lifecycle hook, and the flagged agent integration location is only part of a path classifier. However, Hub authentication forwards an existing GitHub token to an unrestricted MMI\_HUB\_URL override, leaving a concrete conditional credential exposure risk. - **Files touched:** cli/dist/main.cjs - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json declares no lifecycle scripts., The CLI lets MMI\_HUB\_URL override its default Hub endpoint., GitHub credentials can come from environment variables or gh auth token., On a cache miss, Hub authentication posts the GitHub token as a bearer credential to the selected endpoint’s /auth/session route., Hub API callers invoke this authentication helper; the selected endpoint has no destination allowlist., The flagged agent path match is part of a path classifier, not an agent settings write. - **Evidence against:** The default Hub endpoint is fixed in the CLI, and the credential exchange is used to obtain a Hub session., The manifest has no install hook, and the inspected code does not establish credential misuse by the default endpoint. ## Affected versions and remediation This report applies to @mutmutco/claude-plugin@4.5.114. - Review the evidence and your use of @mutmutco/claude-plugin@4.5.114 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.
