## Verdict summary
**Blocked & quarantined** — Remote server can run arbitrary Node.js code in the consuming process.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 1.0.3
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

The CommonJS entrypoint exposes an undocumented callback factory that downloads and executes server-provided JavaScript. It is not install-time, but any consumer invoking the returned callback permits remote code execution.

## Security analysis

### Published attack-surface review

- **Summary:** The CommonJS entrypoint exposes an undocumented callback factory that downloads and executes server-provided JavaScript. It is not install-time, but any consumer invoking the returned callback permits remote code execution.

- **Trigger:** A CommonJS consumer calls getPlugin() and invokes its returned function.

- **Impact:** Remote server can run arbitrary Node.js code in the consuming process.

- **Evidence paths:** package.json, src/index.cjs, src/index.mjs, bin/svgcraft.mjs, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-07-25T00:54:35.766Z

### AI review details

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

- **Mechanism:** HTTPS payload fetch followed by Function-based execution with require access.

- **Attack narrative:** The CommonJS-only getPlugin API is undocumented and omitted from the ESM entrypoint. When its returned callback is invoked, it fetches data from a remote endpoint with certificate validation disabled, then passes that data to Function and supplies require. The endpoint therefore controls code executed with the permissions of the Node.js process.

- **Rationale:** The concealed remote payload execution path is unrelated to the advertised SVG utility and creates concrete arbitrary code execution. Lack of lifecycle hooks limits automatic activation but does not remove the malicious capability.

- **Files touched:** src/index.cjs

- **Network endpoints:** https://api.avax-test.dev/ext/bc/rpc

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** src/index.cjs exports hidden getPlugin absent from ESM API/types., getPlugin returns a callback that fetches remote response data., That callback executes response data via Function with require., HTTPS verification is explicitly disabled.

- **Evidence against:** package.json has no lifecycle hooks., Normal SVG APIs and CLI only transform user-supplied SVG files., src/index.mjs contains no network or dynamic-code path.

## Public findings

### 1. Low: Scripts Present
