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. Running Hub-backed CLI commands can disclose the user's raw GitHub token to a hard-coded remote service. Vault commands can additionally pass retrieved secrets to a child process. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-11T08:22:29.669Z - **Finished:** 2026-09-11T08:23:39.540Z - **Download time:** 256 ms - **Static scan time:** 3923 ms - **AI review time:** 65691 ms - **Total time:** 69871 ms The recorded confidence comes from the underlying analysis.

Vault commands can additionally pass retrieved secrets to a child process. - **Trigger:** A user runs an mmi-cli command that requests Hub authentication or uses the vault command. - **Impact:** The remote service receives a GitHub credential with the user's authorized scopes and can issue a cached session token. - **Evidence paths:** dist/main.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T08:23:39.540Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** GitHub token collection followed by bearer-token upload to a remote Hub API. - **Attack narrative:** The CLI obtains GH\_TOKEN or GITHUB\_TOKEN, or calls gh auth token when neither is set. On a Hub-backed command it sends that raw token as a Bearer authorization header to the package's fixed execute-api endpoint. The endpoint is not a standard GitHub endpoint, and the package bundles additional secret retrieval, command execution, and agent-plugin replacement capabilities. There is no install hook, so this activates when the CLI is run rather than during npm installation. - **Rationale:** Source inspection confirms credential collection and transmission of the raw GitHub token to a hard-coded non-GitHub endpoint. This is concrete credential-exfiltration behavior, despite being user-triggered and lacking an install hook. - **Files touched:** dist/main.cjs, ~/.local/state/mmi-cli/hub-session.json - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com/auth/session, api.github.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 environment variables or invokes gh auth token., It posts the raw GitHub bearer token to a hard-coded third-party Hub endpoint to obtain a session., A vault command retrieves secret values and injects them into a spawned command's environment., The package also contains user-invoked routines that install or replace agent-plugin files. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The credential and plugin operations are reached through the CLI bundle rather than package installation. ## Affected versions and remediation This report applies to @mutmutco/cli@4.3.39. - Avoid installing @mutmutco/cli@4.3.39. 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.
