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 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-22T07:14:40.716Z - **Finished:** 2026-08-22T07:16:06.375Z - **Download time:** 762 ms - **Static scan time:** 1742 ms - **AI review time:** 83154 ms - **Total time:** 85659 ms ## Security analysis ### Published attack-surface review - **Summary:** A loopback agent server can launch Codex with its approval and sandbox protections disabled. The DeepSeek engine can send user-configured credentials to its configured service. - **Trigger:** Starting the native server and submitting an agent request. - **Impact:** A local caller can cause unconstrained agent actions in the selected project. - **Evidence paths:** package.json, dist/scripts/postinstall.js, dist/constant/index.js, dist/server/index.js, dist/agent/engines/codex.js, dist/agent/engines/deepseek.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T07:16:06.375Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Loopback agent API spawning Codex with bypass flags. - **Rationale:** No concrete malicious lifecycle action is established: postinstall only imports a module whose main path is direct-run guarded. However, the intentional unsandboxed Codex execution and permissive local request handling warrant a warning. - **Files touched:** dist/agent/engines/codex.js, dist/server/index.js, dist/agent/engines/deepseek.js, dist/scripts/postinstall.js - **Network endpoints:** https://api.deepseek.com/chat/completions ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Codex engine explicitly invokes Codex with approvals and sandbox bypassed., Loopback server accepts requests with no Origin header., DeepSeek mode sends its configured API key to its configured/default API endpoint. - **Evidence against:** The postinstall hook only imports its module; main runs only when directly executed., Server binds to 127.0.0.1., Codex MCP configuration is supplied as runtime arguments, not by mutating global Codex config. ## Public findings ### 1.
