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:** 90.0% - **Started:** 2026-09-12T20:45:22.397Z - **Finished:** 2026-09-12T20:46:18.725Z - **Download time:** 515 ms - **Static scan time:** 222 ms - **AI review time:** 55590 ms - **Total time:** 56328 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:** A user-started local chat server exposes a route that launches Codex with unrestricted sandbox access. Its default no-token and permissive CORS settings can make that capability reachable by local web content. - **Trigger:** The operator starts the server and a client sends a chat request to its API. - **Impact:** A caller able to reach the server can induce commands and file changes in the configured workspace; configured provider credentials may be used for AI requests. - **Evidence paths:** server/index.js, server/lib/runner.js, server/lib/cors.js, server/lib/gemini-responses.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T20:46:18.725Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Prompt-driven Codex execution with danger-full-access. - **Rationale:** The package contains a real, user-invoked unrestricted coding-agent server with weak default exposure controls. It has no automatic install hook or self-dependency chain, so the source supports a warning rather than a malicious publish block. - **Files touched:** server/index.js, server/lib/runner.js, server/lib/cors.js, server/lib/gemini-responses.js - **Network endpoints:** https://openrouter.ai/api/v1/models, https://generativelanguage.googleapis.com/v1beta ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The chat endpoint passes a request prompt into a Codex child process., The child process runs with full filesystem and command access and bypasses the Git repository safety check., The server accepts chat requests without a token unless the operator configures one; its CORS policy also permits all origins by default., The Gemini adapter embeds instructions to automatically use tools for commands, files, tests, and edits. - **Evidence against:** There is no preinstall, install, or postinstall hook; prepare only builds the package., The dangerous execution path requires an explicit CLI or server start and a chat request., Network calls target configured AI providers or their model catalogs, not an unrelated collection endpoint., The automatic npm install fetches @openai/codex after an explicit server or check action, not this package itself. ## Affected versions and remediation This report applies to @pmcai/codex-chat-widget@0.3.0. - Review the evidence and your use of @pmcai/codex-chat-widget@0.3.0 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.
