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. Invoking authenticated commands can collect a local GitHub credential and transmit it to the package's Hub service. Command invocation also sends usage telemetry by default. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-10T13:06:04.606Z - **Finished:** 2026-09-10T13:07:46.136Z - **Download time:** 514 ms - **Static scan time:** 3494 ms - **AI review time:** 97522 ms - **Total time:** 101530 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:** Invoking authenticated commands can collect a local GitHub credential and transmit it to the package's Hub service. Command invocation also sends usage telemetry by default. - **Trigger:** Run mmi-cli commands that need Hub authentication or any command action. - **Impact:** A third-party Hub receives the user's raw GitHub bearer credential and can use it within that credential's permissions. - **Evidence paths:** dist/main.cjs, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-10T13:07:46.136Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Reads GitHub credentials and posts them to a hard-coded remote Hub endpoint. - **Attack narrative:** The executable loads the command bundle when the user runs mmi-cli. The bundle obtains GH\_TOKEN, GITHUB\_TOKEN, or the result of gh auth token, then posts that credential in an Authorization header to a hard-coded AWS API Gateway Hub endpoint to obtain a session. It also posts command telemetry to the same Hub for every command action unless an environment setting disables it. There is no install hook, but the credential transfer is a concrete user-triggered exfiltration path. - **Rationale:** The package transmits raw GitHub credentials to a hard-coded external service, not merely to GitHub's API. This creates a credential-exfiltration capability whenever authenticated CLI functionality is invoked. - **Files touched:** dist/index.cjs, dist/main.cjs - **Network endpoints:** tqxxwzftic.execute-api.eu-central-1.amazonaws.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **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 raw GitHub credential as a bearer token to its configured Hub session endpoint., Every command action sends telemetry to the Hub by default., Except for version flags, the launcher loads the main CLI bundle. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The bundle is entered through the mmi-cli executable; importing the version path does not load the main command bundle. ## Affected versions and remediation This report applies to @mutmutco/cli@4.3.2. - Avoid installing @mutmutco/cli@4.3.2. 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.
