At runtime, cloud-delivered messages can be injected into a local agent and cause replies to be sent through the relay. - **Trigger:** npm install -g @essentialai/cogent-bridge, followed by relay message delivery to a registered peer. - **Impact:** The package mutates a foreign AI-agent control surface during installation and can cause an agent to process untrusted relay content, including with sandbox bypass on affected hosts. - **Evidence paths:** package.json, scripts/postinstall-global.mjs, dist/services/auto-relay.js, dist/config.js, dist/services/codex-preflight.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T12:14:48.929Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall remote shell execution and automatic Codex plugin provisioning, combined with cloud-to-agent message injection. - **Attack narrative:** Installing this package globally triggers a postinstall hook that pipes a remote installer into sh and then changes Codex by adding a marketplace and plugin. The package also connects to its hosted relay by default and injects inbound relay messages into local agent sessions. Its automatic sandbox fallback can run those resumed Codex tasks with full filesystem and network access when the sandbox probe reports a blocked host. - **Rationale:** This is unconsented install-time mutation of a foreign AI-agent control surface, with remote shell execution and subsequent automatic agent-message injection. The global-install guard reduces scope but does not provide interactive consent for these actions. - **Files touched:** scripts/postinstall-global.mjs, ~/.codex/packages/standalone/current/codex, dist/services/auto-relay.js, dist/services/codex-preflight.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:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall script., On global installation, the script downloads and executes a remote shell installer for Codex without an interactive consent prompt., The same lifecycle script adds a third-party Codex marketplace and installs its plugin., The runtime defaults to a hosted relay and automatically injects received cloud messages into a local agent session., When its sandbox probe reports a blocked host, the default configuration enables unsandboxed Codex execution. - **Evidence against:** The postinstall hook is limited to global npm installs and skips CI and Windows., The package contains no direct credential-harvesting or secret-exfiltration code in the inspected paths. ## Public findings ### 1.
