The remote response is directly piped into a shell. - **Trigger:** npm install when Bun is unavailable - **Impact:** A remotely served installer can execute arbitrary code with the installing user's privileges. - **Evidence paths:** package.json, scripts/install-bun.mjs, scripts/run-nanoagent.mjs, dist/main.js, dist/bun-detect.js, dist/config/load.js, dist/mcp/index.js, dist/tools/mcp-manage.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T19:08:58.738Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote shell execution - **Attack narrative:** npm invokes the declared postinstall hook. The hook tests for Bun and, if absent, fetches a network-hosted installer and immediately executes it through bash (or PowerShell on Windows), with no checksum, version pin, or install-time consent. Compromise or replacement of that remote response yields arbitrary code execution during dependency installation. - **Rationale:** The package contains an unconsented install-time remote code-execution chain. Its runtime safeguards do not mitigate this lifecycle behavior. - **Files touched:** package.json, scripts/install-bun.mjs - **Network endpoints:** https://bun.sh/install ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall runs install-bun.mjs., When Bun is absent, that script downloads and pipes remote content to bash without a pinned artifact or user confirmation. - **Evidence against:** The CLI launcher only starts packaged source/dist entries., Other reviewed network use is provider/model access or explicit skill installation. ## Public findings ### 1.
