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. LPM treats this as warn-only first-party agent extension lifecycle risk. A global install can download and execute Codex's installer and register the vendor's Cogent plugin. During configured cloud use, incoming peer messages can be injected into a local Codex session; no separate theft or destructive payload was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-08-28T08:46:28.473Z - **Finished:** 2026-08-28T08:47:39.299Z - **Download time:** 506 ms - **Static scan time:** 766 ms - **AI review time:** 69553 ms - **Total time:** 70826 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 global install can download and execute Codex's installer and register the vendor's Cogent plugin. During configured cloud use, incoming peer messages can be injected into a local Codex session; no separate theft or destructive payload was found. - **Trigger:** npm install -g activates the guarded postinstall; registered cloud peers activate runtime relay. - **Impact:** It expands the AI-agent control surface and can execute relay prompts with a fallback that removes Codex approval and sandbox controls. - **Evidence paths:** package.json, scripts/postinstall-global.mjs, dist/services/auto-relay.js, dist/services/codex-app-server.js, dist/services/codex-preflight.js, dist/config.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T08:47:39.299Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global Codex plugin provisioning and cloud-to-agent message relay. - **Rationale:** This is a real first-party agent-extension lifecycle and remote-execution capability, so it warrants a warning. It does not meet the blocking policy because the mutation is limited to the vendor's Codex setup rather than a foreign or broad control surface. - **Files touched:** scripts/postinstall-global.mjs, ~/.codex/packages/standalone, ~/.codex/config.toml, dist/services/auto-relay.js, dist/services/codex-app-server.js - **Network endpoints:** https://chatgpt.com/codex/install.sh, https://github.com/eaisdevelopment/cogent.git, https://cogent.tools, https://app.cogent.tools ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Global postinstall runs a remote shell installer for Codex's managed build., The install hook adds a Cogent marketplace and plugin to Codex., Cloud messages are automatically injected into a local agent session and its response is relayed., A blocked sandbox can default to an approval-and-sandbox bypass for relay tasks. - **Evidence against:** The hook is explicitly limited to global installs and skips dependency, npx, CI, and Windows installs., The configured network services and plugin are branded Cogent/Codex components; no unrelated credential theft or destructive payload was found., The runtime installer asks for confirmation before downloading when launched through the user-facing wrapper. ## Affected versions and remediation This report applies to @essentialai/cogent-bridge@3.20.5. - Review the evidence and your use of @essentialai/cogent-bridge@3.20.5 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.
