Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 16 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.18 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Static inspection found an active postinstall that installs the package's matching Hum core and an installer that downloads uv from astral.sh when needed. The scanner's browser credential claim is unsupported by the inspected credential read, which only supports a local sign-in status check; no malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-09T06:53:03.503Z - **Finished:** 2026-10-09T06:53:49.698Z - **Download time:** 1550 ms - **Static scan time:** 5082 ms - **AI review time:** 39562 ms - **Total time:** 46195 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 confirmed attack was identified. The postinstall installs a version-matched Hum core and package under the user's Hum directory. - **Trigger:** npm runs the package's postinstall; the CLI can also install updates when invoked. - **Impact:** This installs and updates the coding agent; inspected source did not establish credential theft or another concrete attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:53:49.698Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer uses uv and npm to install Hum components into versioned directories under the Hum home directory; its npm fetch disables lifecycle scripts. - **Rationale:** Static inspection found an active postinstall that installs the package's matching Hum core and an installer that downloads uv from astral.sh when needed. The scanner's browser credential claim is unsupported by the inspected credential read, which only supports a local sign-in status check; no malicious behavior was established. - **Files touched:** ~/.hum/versions/\, ~/.hum/core-install.json, ~/.hum/update.log - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json runs a postinstall script that invokes the package's core installer., The installer downloads the \`uv\` tool from astral.sh when it is not present and uses it to install the matching \`hum-cli\` Python core., The installer can fetch another release of this same package, with npm lifecycle scripts disabled., The CLI reads credentials.json for a local sign-in status check; inspected code did not show credential transmission. - **Evidence against:** The postinstall's installer targets the package's versioned Hum directory and installs the matching core., The self-package fetch uses the same requested version and passes \`--ignore-scripts\`., The reviewed credential read is used to display sign-in status; no browser credential collection or exfiltration was established. ## Affected versions and remediation This report applies to @metaphi-ai/hum@0.2.18. - Review the evidence and your use of @metaphi-ai/hum@0.2.18 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.
