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 invoked, the CLI can collect an existing GitHub credential and send it to a remote Hub service. It also emits command telemetry by default and can replace its global installation during train operations. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-11T04:57:30.271Z - **Finished:** 2026-09-11T04:58:43.652Z - **Download time:** 765 ms - **Static scan time:** 3484 ms - **AI review time:** 69131 ms - **Total time:** 73381 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 invoked, the CLI can collect an existing GitHub credential and send it to a remote Hub service. It also emits command telemetry by default and can replace its global installation during train operations. - **Trigger:** A user runs an mmi-cli command; Hub-backed commands trigger credential exchange, and train commands can trigger self-update. - **Impact:** A GitHub credential can be disclosed to the remote Hub endpoint, enabling access beyond the user's intended GitHub API calls. - **Evidence paths:** package.json, dist/main.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T04:58:43.652Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** GitHub token forwarding, default telemetry, and global self-update. - **Attack narrative:** The executable loads the main bundle when a user invokes the CLI. The bundle obtains a GitHub token from environment variables or gh auth, then posts it as a bearer token to an AWS-hosted Hub endpoint. A pre-action hook also sends command telemetry for every action unless an opt-out environment variable is set. For selected train commands, stale-version handling globally installs another release of the same package and re-executes the command. - **Rationale:** The package forwards usable GitHub credentials to a remote service under its control and couples this with automatic telemetry and self-updating behavior. Although it lacks install hooks, the credential transfer is a concrete user-triggered exfiltration path. - **Files touched:** dist/index.cjs, dist/main.cjs - **Network endpoints:** tqxxwzftic.execute-api.eu-central-1.amazonaws.com ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The CLI reads GitHub credentials from GH\_TOKEN, GITHUB\_TOKEN, or the local gh CLI., It sends that GitHub token as a bearer credential to the package-controlled Hub endpoint to obtain a session., Every command action sends telemetry to that endpoint by default before the command runs., Stale train commands automatically run a global npm install of this package and then re-execute themselves., The manifest exposes the executable entry point that loads the bundled runtime. - **Evidence against:** There are no npm install lifecycle hooks in package.json., The observed network and process behavior starts only when the user runs the CLI. ## Affected versions and remediation This report applies to @mutmutco/cli@4.3.27. - Avoid installing @mutmutco/cli@4.3.27. 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.
