Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 1.0.58 - **Selected version is latest:** Yes - **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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-08T13:15:04.818Z - **Finished:** 2026-10-08T13:17:21.913Z - **Download time:** 1016 ms - **Static scan time:** 474 ms - **AI review time:** 135604 ms - **Total time:** 137095 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 host provides configuration editing for Claude and Codex agent files, including hook configuration. This is a guarded capability that can affect later agent behavior; the inspected source does not establish an active attack. - **Trigger:** A configuration-write message sent to the host during use of the settings interface. - **Impact:** User-selected edits can change agent instructions, hooks, or plugins and affect later agent runs. - **Evidence paths:** src/host/claude-host.mjs, src/host/codex-host.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-08T13:17:21.913Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The host accepts submitted configuration content and writes it to supported agent configuration files, with project paths constrained to directories opened during the current run. - **Rationale:** The source supports a guarded agent-configuration capability that can alter hooks and other settings, warranting a warning under the agent integration policy. The inspected evidence does not show automatic installation-time mutation or a concrete malicious chain. - **Files touched:** src/host/claude-host.mjs, src/host/codex-host.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes a command-line installer rather than an npm lifecycle hook., The Claude host accepts configuration-write messages for Claude settings, including hooks and enabled plugins., The Codex host maps configuration edits to agent files, including AGENTS.md and hooks.json, and writes the submitted content., Both hosts restrict project configuration paths to directories opened in the current run. - **Evidence against:** The inspected configuration code does not show writes triggered by npm installation., The configuration edits are exposed through the host message interface and are constrained to the selected project or the agent's own configuration directory. ## Affected versions and remediation This report applies to @lizard-build/lizard-studio-host@1.0.58. - Review the evidence and your use of @lizard-build/lizard-studio-host@1.0.58 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.
