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 command can collect an existing GitHub credential and transmit it to a custom AWS endpoint. It also reports command telemetry on command execution by default. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-11T11:44:01.470Z - **Finished:** 2026-09-11T11:46:18.324Z - **Download time:** 762 ms - **Static scan time:** 3357 ms - **AI review time:** 132734 ms - **Total time:** 136854 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 command can collect an existing GitHub credential and transmit it to a custom AWS endpoint. It also reports command telemetry on command execution by default. - **Trigger:** A user runs a Hub-authenticated CLI command after GitHub credentials are available. - **Impact:** The endpoint operator can receive and use the user's GitHub credential. - **Evidence paths:** dist/main.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T11:46:18.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** GitHub token collection followed by a bearer-authenticated POST to the Hub endpoint. - **Attack narrative:** After a user invokes a Hub-authenticated command, the CLI accepts GH\_TOKEN or GITHUB\_TOKEN, or obtains a token through gh auth token. It then posts that token in an Authorization bearer header to its default custom AWS endpoint. This transfers a reusable GitHub credential outside GitHub. Separately, the command pre-action hook sends command, version, CI status, and operating-system telemetry unless the user sets an opt-out environment variable. - **Rationale:** The source directly implements credential collection and transfer to a non-GitHub service. The lack of an install hook limits the trigger but does not remove the credential-exfiltration behavior. - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com/auth/session ### 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 by running gh auth token., It sends that GitHub token as a bearer credential to a non-GitHub default endpoint., A pre-action hook silently sends command telemetry for each CLI command unless disabled. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The credential transfer is reached through Hub authentication code rather than package installation. ## Affected versions and remediation This report applies to @mutmutco/cli@4.3.41. - Avoid installing @mutmutco/cli@4.3.41. 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.
