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. A locally started harness accepts cross-origin requests without authentication by default. A request can cause Codex to execute an agent turn with unrestricted sandbox access in the configured workspace. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-12T21:24:13.789Z - **Finished:** 2026-09-12T21:25:09.593Z - **Download time:** 501 ms - **Static scan time:** 290 ms - **AI review time:** 55012 ms - **Total time:** 55804 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 locally started harness accepts cross-origin requests without authentication by default. A request can cause Codex to execute an agent turn with unrestricted sandbox access in the configured workspace. - **Trigger:** A user starts the server, then a local or browser-originated client creates a session and posts to /api/chat. - **Impact:** An attacker able to reach the local service can induce filesystem and command actions through Codex in its workspace. - **Evidence paths:** server/lib/cors.js, server/index.js, server/lib/runner.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T21:25:09.593Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unauthenticated cross-origin agent execution with a danger-full-access sandbox. - **Rationale:** The package is not shown to be malicious: it has no automatic install hook or package-controlled exfiltration. However, its default CORS and authentication settings expose a high-impact Codex execution endpoint after explicit startup. - **Files touched:** \/workspace, \/data/settings.db, \/.codex-runs/\ - **Network endpoints:** 127.0.0.1, https://openrouter.ai/api/v1, https://generativelanguage.googleapis.com/v1beta ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** The default CORS policy accepts every origin and the default bearer-token gate permits all requests., An unauthenticated chat request is passed to Codex with a danger-full-access sandbox and a supplied workspace., The server persists provider API keys and forwards Gemini requests only to configured provider endpoints. - **Evidence against:** No preinstall, install, or postinstall lifecycle hook is declared; prepare only runs the missing build script., The dangerous execution path requires an explicit CLI/server start and a chat request., No package-controlled exfiltration endpoint, obfuscation, self-dependency, or hidden payload was found. ## Affected versions and remediation This report applies to @pmcai/codex-chat-widget@0.3.7. - Review the evidence and your use of @pmcai/codex-chat-widget@0.3.7 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.
