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. Source confirms conditional forwarding of the saved API key to an unrestricted operator-configured HTTPS endpoint. The endpoint is explicitly configurable for self-hosted use, so this is a credential exposure risk rather than evidence of covert theft or malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-09T04:58:38.415Z - **Finished:** 2026-10-09T04:59:20.739Z - **Download time:** 1027 ms - **Static scan time:** 1613 ms - **AI review time:** 39684 ms - **Total time:** 42324 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 CLI can forward its saved API key to a configurable HTTPS endpoint. This creates conditional credential exposure when the endpoint is set to an untrusted host. - **Trigger:** A CLI operation makes an API request after an endpoint and API key have been configured. - **Impact:** A wrongly configured or malicious endpoint can receive the Mushi API key. - **Evidence paths:** dist/chunk-AHDD44WU.js, dist/chunk-LDPFTQLE.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T04:59:20.739Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Endpoint configuration accepts an environment-provided or explicit URL; API requests attach the configured key in authentication headers. - **Rationale:** Source confirms conditional forwarding of the saved API key to an unrestricted operator-configured HTTPS endpoint. The endpoint is explicitly configurable for self-hosted use, so this is a credential exposure risk rather than evidence of covert theft or malicious intent. - **Network endpoints:** https://dxptnwrhwsqckaftyymj.supabase.co/functions/v1/api ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI accepts an API endpoint from environment configuration alongside the API key and project ID., Requests send the configured endpoint the API key in authentication headers., The endpoint check permits any HTTPS host, without restricting it to the Mushi service., Agent integration setup is exposed as an explicit CLI command; the inspected target locations do not show an install hook. - **Evidence against:** The package has no preinstall, install, or postinstall lifecycle hook., Endpoint selection is configurable for self-hosted use, and the package also provides a default service endpoint., The inspected agent target locations concern setup or detection; they do not establish an automatic foreign agent configuration mutation. ## Affected versions and remediation This report applies to @mushi-mushi/cli@0.30.2. - Review the evidence and your use of @mushi-mushi/cli@0.30.2 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.
