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:** 0.3.8 - **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:** 91.0% - **Started:** 2026-09-12T21:32:34.882Z - **Finished:** 2026-09-12T21:34:00.620Z - **Download time:** 504 ms - **Static scan time:** 259 ms - **AI review time:** 84974 ms - **Total time:** 85738 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:** An explicitly started local server exposes a default unauthenticated, cross-origin chat API that launches a powerful Codex agent. A web page or local process can submit prompts to that agent while it runs with unrestricted sandbox access. - **Trigger:** Start the server, then send requests to its chat API. - **Impact:** An untrusted caller may induce agent actions with filesystem and command access available to the server process. - **Evidence paths:** server/index.js, server/lib/runner.js, server/lib/cors.js, server/lib/gemini-responses.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T21:34:00.620Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cross-origin prompt submission to an unrestricted Codex execution harness. - **Rationale:** This is a concrete unsafe agent-execution surface, but it is activated by an explicit server command rather than package installation and no unrelated exfiltration or stealth persistence was found. - **Files touched:** \/workspace, \/node\_modules, \/../.codex-runs - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The unauthenticated chat endpoint accepts a supplied prompt and passes it to the Codex runner., The runner invokes Codex with danger-full-access sandboxing in the selected workspace., Default CORS accepts every origin and the default bearer token is empty., The Gemini harness prompt grants full execution when a caller's first message contains a special phrase. - **Evidence against:** The manifest has only prepare and prepublish build hooks, not install-time hooks., Provider requests target configured Google AI or OpenRouter APIs; no unrelated exfiltration receiver was found., The fallback Codex installation is triggered by an explicit server or CLI action and is scoped to the chosen runtime home. ## Affected versions and remediation This report applies to @pmcai/codex-chat-widget@0.3.8. - Review the evidence and your use of @pmcai/codex-chat-widget@0.3.8 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.
