## Security analysis

### Published attack-surface review

- **Summary:** npm installation can execute a remote Bun installer without user confirmation. The remote script is not pinned or integrity-verified.

- **Trigger:** npm install of janex-agent when Bun is absent

- **Impact:** A response controlled by the remote installer endpoint executes with the installing user's privileges.

- **Evidence paths:** package.json, scripts/postinstall.mjs, bin/janex.js, dist/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T19:10:44.964Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** postinstall remote download-and-shell execution

- **Attack narrative:** The package's postinstall hook automatically downloads and pipes a remote Bun installer into bash on Unix-like systems, or downloads and executes a PowerShell installer with policy bypass on Windows. This occurs during npm install, before a user invokes Janex, and lacks a pinned artifact or integrity check.

- **Rationale:** Automatic unauthenticated remote code execution in an npm lifecycle hook is a concrete install-time attack surface. Runtime agent tools are package-aligned, but do not mitigate the lifecycle risk.

- **Files touched:** scripts/postinstall.mjs, node\_modules/@opentui/react/chunk-fm0c65gm.js

- **Network endpoints:** https://bun.sh/install, bun.sh/install.ps1

### Review decision

- **Verdict:** Malicious

- **Confidence:** 97.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json invokes postinstall automatically., scripts/postinstall.mjs runs curl https://bun.sh/install | bash on non-Windows when Bun is absent., The same hook runs a PowerShell download-and-execute command with ExecutionPolicy Bypass on Windows., The downloaded installer is unauthenticated and executes during npm installation.

- **Evidence against:** No source evidence that the postinstall harvests credentials or exfiltrates local data., Agent file and shell capabilities are registered for explicit Janex runtime use, not invoked by installation.
