## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. Installation can download configured browser binaries, which is Puppeteer's documented package function.

- **Trigger:** npm postinstall, or explicit puppeteer CLI use.

- **Impact:** Downloads browser artifacts when download is not disabled; no source evidence of data theft or unauthorized system/control-surface mutation.

- **Evidence paths:** package.json, install.mjs, lib/puppeteer/node/install.js, lib/puppeteer/getConfiguration.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-27T13:10:00.134Z

### AI review details

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

- **Mechanism:** Configured browser download and cache setup.

- **Rationale:** The lifecycle hook is a package-aligned browser provisioning step with user-configurable skip, proxy, cache, and download settings. Source inspection found no concrete malicious behavior.

- **Files touched:** package.json, install.mjs, lib/puppeteer/node/install.js, lib/puppeteer/getConfiguration.js, lib/puppeteer/node/cli.js, lib/puppeteer/puppeteer.js

### Review decision

- **Verdict:** Clean

- **Confidence:** 98.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json postinstall only runs node install.mjs., install.mjs imports the packaged browser installer., lib/puppeteer/node/install.js downloads configured Chrome/Firefox builds via @puppeteer/browsers., Environment variables configure browser, cache, proxy, and optional download URL; none are harvested or exfiltrated., No shell execution, eval/vm, credential access, persistence, or agent-control writes found in package sources.
