Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The source supports a conditional credential-exposure risk because an environment override can redirect the GitHub token exchange to an unrestricted origin. The default is the package Hub, the agent-config match is a path classifier, and package.json has no lifecycle scripts; the evidence does not support blocking the release. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-18T14:47:37.941Z - **Finished:** 2026-10-18T14:49:11.187Z - **Download time:** 1031 ms - **Static scan time:** 4296 ms - **AI review time:** 87918 ms - **Total time:** 93246 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:** A Hub-backed CLI command can expose a GitHub token when MMI\_HUB\_URL is set to an unrestricted custom origin. The default endpoint is the package's Hub, and no covert default transfer was identified. - **Trigger:** A user runs a Hub-backed command while MMI\_HUB\_URL points to a custom origin. - **Impact:** The configured recipient can receive the GitHub token, creating conditional credential exposure. - **Evidence paths:** cli/dist/main.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-18T14:49:11.187Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI obtains a GitHub token from the environment or GitHub CLI and sends it as bearer authorization to that origin's session endpoint without an origin allowlist in the inspected path. - **Rationale:** The source supports a conditional credential-exposure risk because an environment override can redirect the GitHub token exchange to an unrestricted origin. The default is the package Hub, the agent-config match is a path classifier, and package.json has no lifecycle scripts; the evidence does not support blocking the release. - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest declares no lifecycle scripts, so the token exchange is not triggered by package installation., The CLI reads a GitHub token from environment variables or the GitHub CLI., Hub authentication sends that token as a bearer credential to the configured Hub session endpoint. MMI\_HUB\_URL can replace the package's default Hub URL, and the inspected exchange has no origin allowlist., Hub client wrappers pass the token into this exchange for Hub-backed commands; whoami also calls the session helper., The reported Codex path match is a repository path classifier used to identify uncommittable agent-config paths, not a configuration write., Separate CLI telemetry is triggered by a CLI command and sends command, version, CI status, and operating system metadata to the default Hub. ## Affected versions and remediation This report applies to @mutmutco/codex-plugin@4.5.149. - Review the evidence and your use of @mutmutco/codex-plugin@4.5.149 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
