Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall and subprocess behavior serve the package’s own versioned core setup, and the CLI delegates work to that core when launched. Although the bootstrap executes an upstream installer, inspected source did not show a concrete attack chain or credential exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-09T06:54:27.176Z - **Finished:** 2026-10-09T06:55:10.389Z - **Download time:** 772 ms - **Static scan time:** 4839 ms - **AI review time:** 37601 ms - **Total time:** 43213 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:** No attack was identified in the inspected source. The automatic installer bootstraps Hum’s core, and the CLI starts that core when invoked. - **Trigger:** npm installation runs the postinstall script; launching \`hum\` starts the CLI session. - **Impact:** The inspected behavior sets up and runs the package’s own product; no concrete malicious impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:55:10.389Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer invokes the Astral uv bootstrap when uv is absent, then installs Hum’s versioned Python core. The CLI delegates session work to that core. - **Rationale:** The postinstall and subprocess behavior serve the package’s own versioned core setup, and the CLI delegates work to that core when launched. Although the bootstrap executes an upstream installer, inspected source did not show a concrete attack chain or credential exfiltration. - **Files touched:** ~/.hum/versions/\/core, ~/.hum/versions/\/pkg - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json links the CLI to a postinstall script and the \`hum\` launcher., dist/install.mjs uses the upstream Astral installer to bootstrap uv, then installs Hum’s Python core into a version-specific directory., dist/cli.mjs starts the core when a session is invoked; the inspected source did not establish credential harvesting or an unrelated exfiltration path. - **Evidence against:** The postinstall runs a shell command that pipes the Astral-hosted uv installer into the shell; this is automatic bootstrap behavior but is consistent with setting up Hum’s core. ## Affected versions and remediation This report applies to @metaphi-ai/hum@0.2.23. - Review the evidence and your use of @metaphi-ai/hum@0.2.23 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.
