Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. When a Hub-authenticated command runs, the CLI obtains a GitHub token and transmits it to its default Hub endpoint. It also installs or replaces vendor plugins through an explicit doctor/heal path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-10T12:52:44.251Z - **Finished:** 2026-09-10T12:54:35.989Z - **Download time:** 251 ms - **Static scan time:** 2970 ms - **AI review time:** 108517 ms - **Total time:** 111738 ms The recorded confidence comes from the underlying analysis.

It also installs or replaces vendor plugins through an explicit doctor/heal path. - **Trigger:** Run a command that requests Hub authentication, or run the doctor or plugin-heal flow. - **Impact:** A GitHub credential is disclosed to the remote Hub service; plugin management can alter supported AI-agent configuration. - **Evidence paths:** dist/main.cjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-10T12:54:35.989Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** GitHub token session exchange and vendor plugin management. - **Attack narrative:** The CLI obtains a GitHub token from GH\_TOKEN, GITHUB\_TOKEN, or \`gh auth token\`, then posts it as a bearer credential to an AWS API endpoint outside GitHub. The same bundle sends default-on telemetry and contains commands that remove, add, and install the vendor's Codex or Claude plugins. There is no npm install lifecycle hook, but the credential transmission is a concrete runtime exposure to a remote service. - **Rationale:** The source directly transfers a GitHub credential to an opaque remote endpoint. Although the package is a user-invoked CLI and lacks install hooks, this is concrete credential exfiltration rather than a harmless scanner primitive. - **Files touched:** ~/.local/state/mmi-cli/hub-session.json, ~/.codex, ~/.claude - **Network endpoints:** tqxxwzftic.execute-api.eu-central-1.amazonaws.com ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The CLI reads GitHub credentials from environment variables or the local GitHub CLI., It sends the GitHub token as a bearer credential to a non-GitHub AWS endpoint to obtain a session., Every CLI command posts usage telemetry by default., The doctor flow can replace and install this vendor's plugins in Codex and Claude. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The package exposes a user-invoked CLI binary rather than import-time execution. ## Affected versions and remediation This report applies to @mutmutco/cli@4.3.0. - Avoid installing @mutmutco/cli@4.3.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
