## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 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:** 0.2.39
- **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 install path executes a remote installer when uv is missing, creating a concrete but product-related remote execution risk. The inspected source does not establish a malicious payload or justify blocking publication.

## Latest scan

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:** Installation can trigger setup that downloads and executes the uv installer from astral.sh, then installs Hum's Python core.

- **Trigger:** The npm postinstall hook runs when the package is installed and the matching core version is not already installed.

- **Impact:** The remote installer executes with the installer's user privileges; the inspected code does not establish malicious behavior by that installer.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T06:56:44.287Z

### AI review details

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

- **Mechanism:** The setup invokes a shell or PowerShell command that pipes the remote installer into a shell or expression evaluator, then uses uv to create an environment and install the core.

- **Rationale:** The automatic install path executes a remote installer when uv is missing, creating a concrete but product-related remote execution risk. The inspected source does not establish a malicious payload or justify blocking publication.

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

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

### 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 when the package is installed., The postinstall script invokes core setup when the installed core version differs., Core setup can run a shell command that downloads and executes an installer from astral.sh., Core setup also creates a Python environment and installs the package's core component.

- **Evidence against:** The setup code installs the stated Python environment and core component under the user's Hum directory., A later package fetch uses the same package name and disables npm lifecycle scripts.
