Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 3.19.10 - **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. No concrete malicious chain was found, but the CLI explicitly installs remotely supplied AI-agent content into project control paths with non-enforcing integrity verification. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-08-13T09:05:10.874Z - **Finished:** 2026-08-13T09:07:54.813Z - **Download time:** 506 ms - **Static scan time:** 674 ms - **AI review time:** 162758 ms - **Total time:** 163939 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:** User-invoked init/sync downloads and installs a remote AI pack under the project .claude directory. The package permits that pack when its server does not provide a digest. - **Trigger:** User runs avatar init or avatar sync. - **Impact:** A compromised or altered approved pack endpoint could affect the configured project AI-agent surface. - **Evidence paths:** README.md, bin/postinstall.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T09:07:54.813Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote AI-pack download and project agent-extension setup - **Rationale:** No concrete malicious chain was found, but the CLI explicitly installs remotely supplied AI-agent content into project control paths with non-enforcing integrity verification. - **Files touched:** .claude/pack/, bin/postinstall.js, dist/lib/print-welcome-screen.js - **Network endpoints:** https://qpdbkewtpkkbcrptnlos.supabase.co/functions/v1/get-pack ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Explicit avatar init/sync downloads a remote AI pack into .claude/pack., Remote-pack integrity check is soft; installation continues without a digest., Install-time postinstall executes only the bundled welcome-screen importer. - **Evidence against:** No credential harvesting or outbound exfiltration path was found in the inspected install hook., Network, shell, and filesystem operations implement documented CLI commands, not automatic install behavior., No eval, remote code execution, or unconsented install-time AI-agent configuration write was found. ## Affected versions and remediation This report applies to @nalvietnam/avatar-cli@3.19.10. - Review the evidence and your use of @nalvietnam/avatar-cli@3.19.10 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.
