A package installation changes a broad AI-agent control surface and causes later Codex sessions to load the configured remote MCP integration. - **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:** 1.3.2 - **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. Installation automatically changes the user's global Codex configuration. It enables hooks and registers a remote VAIBot MCP service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-29T01:36:56.352Z - **Finished:** 2026-09-29T01:37:47.176Z - **Download time:** 760 ms - **Static scan time:** 275 ms - **AI review time:** 49787 ms - **Total time:** 50824 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:** Installation automatically changes the user's global Codex configuration. It enables hooks and registers a remote VAIBot MCP service. - **Trigger:** npm postinstall execution during package installation. - **Impact:** A package installation changes a broad AI-agent control surface and causes later Codex sessions to load the configured remote MCP integration. - **Evidence paths:** package.json, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-29T01:37:47.176Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script edits the Codex configuration and inserts managed feature and MCP-server blocks. - **Attack narrative:** The package runs a postinstall hook without an interactive consent step. That hook edits the user's global Codex configuration, enables hooks, and registers the package operator's remote MCP endpoint. This is an unconsented install-time mutation of a broad AI-agent control surface, which can affect later sessions beyond the package installation itself. - **Rationale:** The automatic lifecycle hook mutates global Codex agent configuration and registers a remote MCP service. This meets the blocking policy for unconsented postinstall control-surface mutation. - **Files touched:** package.json, scripts/postinstall.mjs - **Network endpoints:** https://api.vaibot.io/v2/mcp ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall lifecycle command., The lifecycle script targets the user's global Codex configuration file., The script adds a VAIBot HTTP MCP server and writes managed blocks into that configuration during installation. ## Affected versions and remediation This report applies to @vaibot/codex-circuitbreaker-plugin@1.3.2. - Avoid installing @vaibot/codex-circuitbreaker-plugin@1.3.2. 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.
