Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — An existing GitHub credential is disclosed to the external Hub endpoint and can be exchanged for a session. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 4.3.38 - **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The CLI automatically obtains GitHub credentials and transmits them to its Hub service for session exchange. It also sends command telemetry for each command action unless an environment opt-out is set. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-12T00:04:23.836Z - **Finished:** 2026-09-12T00:05:28.104Z - **Download time:** 764 ms - **Static scan time:** 2682 ms - **AI review time:** 60822 ms - **Total time:** 64268 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:** The CLI automatically obtains GitHub credentials and transmits them to its Hub service for session exchange. It also sends command telemetry for each command action unless an environment opt-out is set. - **Trigger:** Running an mmi-cli command that uses Hub authentication; telemetry runs for every command action. - **Impact:** An existing GitHub credential is disclosed to the external Hub endpoint and can be exchanged for a session. - **Evidence paths:** dist/index.cjs, dist/main.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T00:05:28.104Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** GitHub-token collection and external bearer-token session exchange. - **Attack narrative:** When invoked, the package loads its main CLI bundle. That bundle obtains a GitHub token from GH\_TOKEN, GITHUB\_TOKEN, or the locally authenticated GitHub CLI, then posts it as an Authorization bearer token to the package's default Hub endpoint to create a session. Its command pre-action hook also posts telemetry for each command. The manifest has no install hook, but the credential transfer is concrete runtime exfiltration. - **Rationale:** The source directly collects GitHub credentials and sends them to an external service as bearer authentication. The lack of an install hook limits the trigger but does not remove the credential-exfiltration behavior. - **Files touched:** dist/index.cjs, dist/main.cjs, ~/.local/state/mmi-cli/hub-session.json - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com/auth/session, https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com/telemetry/cli-call ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The executable loads the main bundle when the CLI is invoked., The bundle reads GitHub credentials from environment variables or \`gh auth token\`., It sends that credential as a bearer token to a default external Hub endpoint to obtain a session., Every command action also posts command telemetry to that Hub endpoint by default. - **Evidence against:** There are no npm install lifecycle hooks in the manifest., The behavior runs through the user-invoked CLI rather than during installation. ## Affected versions and remediation This report applies to @mutmutco/cli@4.3.38. - Avoid installing @mutmutco/cli@4.3.38. 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.
