AI Security Review

scanned 27d ago · by lpm-firewall-ai

A package installation can alter the host by installing compiler packages and browser system dependencies. It also downloads a browser binary during postinstall.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Installing the package on Linux as root when required tools are absent; postinstall runs on every install unless opted out.

Impact

Unconsented host-level package installation and network retrieval during dependency installation.

Mechanism

Lifecycle hooks invoke operating-system package managers and Playwright's browser installer.

Attack narrative

On installation, npm runs the package's preinstall and postinstall hooks. On a root Linux host with missing compiler tools, preinstall selects and runs a system package manager, including an index update where applicable. Postinstall invokes Playwright to download Chromium and, as root on Linux, asks it to install browser system dependencies. These host mutations occur automatically as part of installation rather than through an explicit package command.

AI rationale

The package contains concrete, automatic install-time host mutation and network download behavior. Although the implementation is readable and no credential theft was found in the inspected hooks, this is unsafe lifecycle-hook abuse.

3 * postinstall 钩子：确保 Playwright Chromium 已就绪。

4 *

5 * 背景：npm 包不携带浏览器二进制，Linux 上安装 bridge 后 agent 启动浏览器会报

6 * 「Playwright 浏览器没有安装」。本脚本在 npm install 时自动下载 Chromium，

7 * 保证 `npm install -g aws-runtime-bridge` 后浏览器立即可用。

8 *

9 * 策略：

10 * - Linux + root（如 sudo npm install -g）：`install --with-deps chromium`，
