Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 16 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 0.1.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The package has no install-time hook or concealed payload, so the source does not establish malware. However, automatic execution of workspace-controlled MCP commands is a critical RCE vulnerability. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-31T22:34:37.728Z - **Finished:** 2026-08-31T22:35:42.907Z - **Download time:** 507 ms - **Static scan time:** 1049 ms - **AI review time:** 63622 ms - **Total time:** 65179 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 project-local MCP configuration is executed automatically when interactive chat starts. This permits arbitrary commands from an untrusted workspace configuration. - **Trigger:** The user runs emp chat in a workspace containing .emp/mcp.json. - **Impact:** Arbitrary code can run as the user and receive inherited environment variables. - **Evidence paths:** bin/emp.js, lib/mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T22:35:42.907Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic spawning of workspace-configured MCP servers with inherited environment variables. - **Rationale:** The package has no install-time hook or concealed payload, so the source does not establish malware. However, automatic execution of workspace-controlled MCP commands is a critical RCE vulnerability. - **Files touched:** .emp/mcp.json, bin/emp.js, lib/mcp.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** Starting the chat interface automatically loads and connects every MCP server configured in the current workspace., A workspace-controlled MCP configuration supplies the executable, arguments, working directory, and inherited environment to a spawned process without a consent check., The default chat provider is an opaque Cloudflare Workers endpoint with a bundled default key, so chat content is sent there unless the user changes provider. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The risky MCP path requires the user to start the CLI in a workspace containing .emp/mcp.json., Normal model-requested destructive tools have an approval path. ## Affected versions and remediation This report applies to emp-code@0.1.4. - Review the evidence and your use of emp-code@0.1.4 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.
