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 postinstall performs conditional setup for the package’s own core, but it may execute a remote installer through a shell pipeline. That warrants a warning for the automatic remote-code installation surface; the inspected source does not establish a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-09T06:55:29.229Z - **Finished:** 2026-10-09T06:55:59.558Z - **Download time:** 765 ms - **Static scan time:** 734 ms - **AI review time:** 28829 ms - **Total time:** 30329 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:** The automatic postinstall can install uv by piping a remote installer script to a shell, then install Hum’s Python core into its versioned user directory. This creates a conditional remote-code installation surface, but the inspected source does not establish malicious behavior. - **Trigger:** Installing the npm package when the requested Hum core version is not already installed and uv is unavailable. - **Impact:** The installer can execute code obtained from astral.sh and add Hum’s core to the user’s local Hum installation. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:55:59.558Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer invokes a shell or PowerShell command to fetch and execute the uv installer, then uses uv to create an environment and install the Hum core. - **Rationale:** The postinstall performs conditional setup for the package’s own core, but it may execute a remote installer through a shell pipeline. That warrants a warning for the automatic remote-code installation surface; the inspected source does not establish a concrete attack. - **Files touched:** package.json, scripts/postinstall.js, dist/install.mjs - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json registers a postinstall script that runs scripts/postinstall.js., The postinstall handler calls installCore when the requested core version is not installed., installCore runs a shell or PowerShell command that pipes a script from astral.sh directly to a shell when uv is absent., The installer creates a Python environment and installs the Hum core into a versioned directory under the user’s Hum home. - **Evidence against:** The installer targets Hum’s own core and versioned package directories; the inspected code does not show mutation of a foreign or broad AI-agent control surface., The evidence shows no credential harvesting, unrelated data exfiltration, or destructive behavior. ## Affected versions and remediation This report applies to @metaphi-ai/hum@0.2.32. - Review the evidence and your use of @metaphi-ai/hum@0.2.32 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.
