## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 16 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 0.2.19
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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 automatic postinstall can execute a network-fetched installer through a shell when uv is absent, so a warning is warranted. Inspected behavior points to runtime setup, and the source did not confirm the scanner's browser credential theft claim or a malicious self-dependency lifecycle chain.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 85.0%

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:** Automatic installation can run a downloaded installer to provision the Hum runtime. This is an install-time code execution risk, but the inspected flow is consistent with setting up the package's core and does not establish a concrete attack.

- **Trigger:** npm postinstall when the Hum core is not already installed; the shell download occurs if uv is unavailable.

- **Impact:** Downloaded installer code executes with the installing user's privileges; no credential theft or unrelated control-surface mutation was established.

- **Evidence paths:** package.json, scripts/postinstall.js, dist/install.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T06:53:40.583Z

### AI review details

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

- **Mechanism:** The installer runs the Astral uv install script through a shell, then uses uv to create a Python environment and install the Hum core.

- **Rationale:** The automatic postinstall can execute a network-fetched installer through a shell when uv is absent, so a warning is warranted. Inspected behavior points to runtime setup, and the source did not confirm the scanner's browser credential theft claim or a malicious self-dependency lifecycle chain.

- **Files touched:** ~/.hum

- **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh, https://hum.metaphi.ai

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 85.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The manifest runs a postinstall script automatically., The installer can download and execute Astral's installer through a shell during core setup., The installer fetches this package's own release with npm lifecycle scripts disabled., The bundled CLI uses the Hum service as its default distribution host.

- **Evidence against:** The inspected installer path provisions the package's Python core and stores it under the user's Hum directory., The inspected installer fetches the same package release and passes --ignore-scripts; the self-dependency lifecycle chain was not established., The browser credential phishing hint was not corroborated in the inspected source.
