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. The explicitly started local server accepts cross-origin unauthenticated chat requests by default. Those requests can cause Codex to execute attacker-selected prompts with unrestricted sandbox access in its configured workspace. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T21:07:51.280Z - **Finished:** 2026-09-12T21:08:42.960Z - **Download time:** 508 ms - **Static scan time:** 253 ms - **AI review time:** 50918 ms - **Total time:** 51680 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 explicitly started local server accepts cross-origin unauthenticated chat requests by default. Those requests can cause Codex to execute attacker-selected prompts with unrestricted sandbox access in its configured workspace. - **Trigger:** A user starts the server, then a local or cross-origin client creates a session and posts to /api/chat. - **Impact:** Remote code execution and file modification within the harness workspace and any resources accessible to the spawned Codex process. - **Evidence paths:** server/lib/runner.js, server/lib/cors.js, server/lib/gemini-responses.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T21:08:42.960Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unauthenticated cross-origin prompt-to-Codex execution with danger-full-access. - **Rationale:** This is a concrete, remotely triggerable local-agent execution vulnerability, not evidence of install-time malware or credential collection. The default cross-origin and no-token configuration combines with unrestricted Codex execution. - **Files touched:** \/workspace, \/data, \/.codex, \/node\_modules - **Network endpoints:** http://127.0.0.1:4231, https://openrouter.ai/api/v1, https://generativelanguage.googleapis.com/v1beta ### Review decision - **Verdict:** Suspicious - **Confidence:** 98.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** The chat endpoint launches Codex with the danger-full-access sandbox and passes it an HTTP-supplied prompt., The server permits every origin and permits requests without a bearer token by default, enabling a web page to drive the local agent., The Gemini adapter embeds a magic phrase that grants a chat user full execution privileges. - **Evidence against:** There is no preinstall, install, or postinstall lifecycle hook; prepare only runs the package build command., Observed API calls target configured AI providers or the local server, not a package-owned collection endpoint. ## Affected versions and remediation This report applies to @pmcai/codex-chat-widget@0.3.3. - Review the evidence and your use of @pmcai/codex-chat-widget@0.3.3 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.
