Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 17 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:** 1.11.1 - **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 default network binding and empty API key expose administrative CAD/LISP operations to reachable clients, a concrete security risk. The source includes a warning, but the unsafe defaults remain; the result is a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-22T02:52:38.364Z - **Finished:** 2026-10-22T02:54:15.565Z - **Download time:** 780 ms - **Static scan time:** 3662 ms - **AI review time:** 92757 ms - **Total time:** 97201 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:** The server defaults to listening on all network interfaces without authentication. Unauthenticated clients can receive admin access and invoke CAD/LISP operations. - **Trigger:** The server starts with its default host and API key settings, and a network client can reach the bound address. - **Impact:** A reachable unauthenticated client can perform CAD/LISP operations through the server. - **Evidence paths:** package.json, dist/atlisp-mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T02:54:15.565Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The default host is 0.0.0.0 and the API key is empty; with authentication unconfigured, the source assigns the admin role and starts the listener. - **Rationale:** The default network binding and empty API key expose administrative CAD/LISP operations to reachable clients, a concrete security risk. The source includes a warning, but the unsafe defaults remain; the result is a warning rather than a block. - **Network endpoints:** 0.0.0.0 ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The package entrypoint loads the bundled server, whose default HTTP configuration binds to 0.0.0.0 with no API key., When authentication is absent, the server assigns the admin role; its own warning says reachable network clients can perform CAD/LISP operations., The server listens on the configured host and port, so the unauthenticated default exposes those operations beyond loopback. - **Evidence against:** The source warns about unauthenticated non-loopback access and recommends configuring an API key or binding to loopback., Autostart installation is activated through an explicit command-line option. ## Affected versions and remediation This report applies to @atlisp/mcp@1.11.1. - Review the evidence and your use of @atlisp/mcp@1.11.1 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.
