Future Codex launches connect to the managed local app-server; setup also enables startup. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.0-beta.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Global installation automatically changes the user-wide Codex app-server connection setting. This affects a foreign agent control surface beyond the package's own extension directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-30T19:57:15.083Z - **Finished:** 2026-09-30T19:59:20.756Z - **Download time:** 2073 ms - **Static scan time:** 3313 ms - **AI review time:** 120286 ms - **Total time:** 125673 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:** Global installation automatically changes the user-wide Codex app-server connection setting. This affects a foreign agent control surface beyond the package's own extension directory. - **Trigger:** Global npm installation followed by successful automatic setup. - **Impact:** Future Codex launches connect to the managed local app-server; setup also enables startup. - **Evidence paths:** package.json, tools/postinstall.mjs, dist/bin/codex-remote.mjs, dist/src/platform/windows/user-environment.mjs, dist/src/platform/windows/user-environment.ps1, dist/src/managed-app-server.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-30T19:59:20.756Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes setup, which persists CODEX\_APP\_SERVER\_WS\_URL through PowerShell without a separate confirmation. - **Attack narrative:** Global installation automatically invokes setup. Once the managed app-server is ready, setup enables startup and writes a persistent user-wide Codex connection setting. The existing-value guard limits overwrites but still permits automatic mutation when the setting is absent. This crosses the boundary from package-owned setup into changing another agent's control surface without explicit confirmation. - **Rationale:** The inspected lifecycle chain performs an unconsented install-time mutation of a foreign AI-agent control surface, meeting the blocking policy. The local destination and overwrite guard limit the impact but do not remove that behavior. - **Files touched:** managed-environment.json - **Network endpoints:** ws://127.0.0.1:45839 ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json registers an automatic postinstall hook., On global installation, postinstall runs setup and skill-install without a confirmation flag., Setup enables startup and calls configureManagedEnvironment automatically., The environment helper sets CODEX\_APP\_SERVER\_WS\_URL to the managed server address., PowerShell persists the connection setting in the user-wide environment and broadcasts the change., The destination is the local managed app-server at ws://127.0.0.1:45839. - **Evidence against:** The helper refuses to overwrite a different existing user connection setting., The destination is local; the inspected chain does not establish credential exfiltration. ## Affected versions and remediation This report applies to @walkhi/code-relax@0.1.0-beta.1. - Avoid installing @walkhi/code-relax@0.1.0-beta.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
