Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection shows credential handling and reporting tied to the resolved API endpoint, with report transmission gated by user choice. The findings do not establish an unrelated credential recipient or a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-28T03:43:21.884Z - **Finished:** 2026-10-28T03:45:18.031Z - **Download time:** 520 ms - **Static scan time:** 1938 ms - **AI review time:** 113688 ms - **Total time:** 116147 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:** No attack was identified in the inspected source. The CLI sends credentials to the configured Mushi API endpoint as part of setup and report submission. - **Trigger:** A user invokes the setup command; report sending requires an affirmative option or prompt response. - **Impact:** No confirmed attack impact was established; the inspected network behavior supports the CLI’s setup and reporting functions. - **Review source:** ai\_review - **Reviewed:** 2026-10-28T03:45:18.031Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Setup chooses a command-line, environment, or saved endpoint and verifies acquired credentials there. The optional report request sends the project SDK key to that endpoint. - **Rationale:** Source inspection shows credential handling and reporting tied to the resolved API endpoint, with report transmission gated by user choice. The findings do not establish an unrelated credential recipient or a concrete attack. - **Files touched:** package.json, dist/index.js, dist/init.js, dist/chunk-VBEYT4RS.js, dist/chunk-67WU4UYB.js - **Network endpoints:** https://dxptnwrhwsqckaftyymj.supabase.co/functions/v1/api ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a CLI entrypoint and the reviewed dependencies are prompt, command-parsing, and keyring packages., Setup selects the endpoint from the command option, environment, or saved configuration, then acquires and verifies credentials against that endpoint., Test reports send project credentials to the resolved API endpoint only after an explicit send option, --yes, or prompt confirmation; setup can also disable sending., The CLI’s default API endpoint is its service endpoint, and the CLI labels endpoint overrides as intended for self-hosting. - **Evidence against:** No inspected source established credential forwarding to an unrelated recipient or an unconsented installation-time attack. ## Affected versions and remediation This report applies to @mushi-mushi/cli@0.34.1. - Review the evidence and your use of @mushi-mushi/cli@0.34.1 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.
