## Verdict summary
**Blocked & quarantined** — Remote service content can execute code in the connected CAD process with the user's permissions.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 1.11.4
- **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The default-on runtime path executes unverified remote code inside CAD, establishing a concrete remote code execution surface. This supports blocking publication regardless of the package's CAD integration purpose.

## Latest scan

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:** CAD setup automatically fetches and evaluates remote AutoLISP code when automatic installation is enabled, which is the default. The package does not verify the fetched code before execution.

- **Trigger:** A CAD handler connects to CAD while the @lisp core is absent and automatic installation remains enabled.

- **Impact:** Remote service content can execute code in the connected CAD process with the user's permissions.

- **Evidence paths:** dist/atlisp-mcp.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T11:32:04.753Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The bootstrap sends a CAD macro that fetches a response over HTTP and evaluates it inside CAD; initialization fetches and evaluates a response from a second endpoint.

- **Attack narrative:** A CAD handler can trigger the default-on bootstrap after connecting. When the @lisp core is absent, the package sends a macro to CAD that fetches remote AutoLISP over HTTP and evaluates the response directly. The initializer repeats this behavior against a second endpoint, allowing remote code to run in the CAD process.

- **Rationale:** The default-on runtime path executes unverified remote code inside CAD, establishing a concrete remote code execution surface. This supports blocking publication regardless of the package's CAD integration purpose.

- **Network endpoints:** http://atlisp.cn/@, http://atlisp.cn/cloud

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The manifest exposes dist/atlisp-mcp.js as the package entrypoint., Automatic @lisp installation defaults to enabled; wrapped CAD handlers connect before running their requested action, and the connection helper starts installation when enabled., If the @lisp core is missing, the bootstrap sends its installer code to CAD., The installer fetches code from atlisp.cn over HTTP and evaluates the response; initialization does the same with a second endpoint., The bootstrap passes the code directly to CAD's command execution API.

## Affected versions and remediation

This report applies to @atlisp/mcp@1.11.4.

- Avoid installing @atlisp/mcp@1.11.4. 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.
