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. Hub-backed CLI activity obtains a GitHub credential and sends it to a vendor-controlled Hub endpoint. A stale train command can also replace the global CLI and re-run the requested command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-11T04:54:19.154Z - **Finished:** 2026-09-11T04:55:25.081Z - **Download time:** 763 ms - **Static scan time:** 3664 ms - **AI review time:** 61500 ms - **Total time:** 65927 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:** Hub-backed CLI activity obtains a GitHub credential and sends it to a vendor-controlled Hub endpoint. A stale train command can also replace the global CLI and re-run the requested command. - **Trigger:** A user runs a Hub-backed command with GH\_TOKEN, GITHUB\_TOKEN, or a logged-in gh CLI; the update path requires a stale train command. - **Impact:** The remote Hub receives a usable GitHub credential; the updater changes the globally installed CLI. - **Evidence paths:** dist/main.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T04:55:25.081Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** GitHub token forwarding to a remote session endpoint and global self-update. - **Attack narrative:** On a Hub-backed CLI path, the package reads GH\_TOKEN, GITHUB\_TOKEN, or executes gh auth token. It then sends that credential in an Authorization header to the package's default AWS Hub endpoint. Separately, a stale train command invokes npm install -g for a selected @mutmutco/cli release and re-executes the command. There is no install lifecycle trigger, but the credential forwarding is a concrete remote credential-exfiltration surface when users invoke affected commands. - **Rationale:** The source directly forwards locally available GitHub credentials to a non-GitHub default endpoint. The lack of lifecycle hooks reduces propagation risk but does not remove the credential-exfiltration behavior. - **Files touched:** 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 gh login., It posts the GitHub token as a Bearer credential to the package's default Hub endpoint., A stale train command can globally install and re-execute a selected release of this CLI. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The credential and update paths are reached through CLI commands, not package installation or import alone. ## Affected versions and remediation This report applies to @mutmutco/cli@4.3.23. - Avoid installing @mutmutco/cli@4.3.23. 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.
