## Verdict summary
**Blocked & quarantined** — Remote code can run in a page/runner context, while browser identity, page context, and optional location are transmitted to the vendor service.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 0.2.2
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

At runtime the SDK registers a detailed browser/device profile and accepts WebSocket work containing a tracking-script URL. It then executes that remote script through a hosted runner or script injection.

## Security analysis

### Published attack-surface review

- **Summary:** At runtime the SDK registers a detailed browser/device profile and accepts WebSocket work containing a tracking-script URL. It then executes that remote script through a hosted runner or script injection.

- **Trigger:** A consumer initializes the SDK; the orchestrator sends a request with trackingScript.

- **Impact:** Remote code can run in a page/runner context, while browser identity, page context, and optional location are transmitted to the vendor service.

- **Evidence paths:** package.json, bin/zerogpu.mjs, dist/extension/zerogpu-offscreen.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-20T10:56:50.492Z

### AI review details

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

- **Mechanism:** Server-directed remote script execution plus browser-profile collection.

- **Attack narrative:** On SDK initialization, the package builds a detailed profile including user/device identifiers, URL/referrer, and optional location, then posts it to the vendor orchestrator. Runtime WebSocket requests may include trackingScript; the package passes that URL to a hosted runner or injects it as a script element, explicitly treating successful load as execution. The package also offers an explicit CLI that modifies an extension manifest for broad host access and automatic startup.

- **Rationale:** The package contains a concrete server-directed remote-code execution path and substantial browser-context collection. Its lifecycle hook is not install-time, but that does not mitigate the runtime payload mechanism.

- **Files touched:** package.json, bin/zerogpu.mjs, dist/extension/zerogpu-offscreen.js

- **Network endpoints:** https://devices.zerogpu.ai, https://zerogpu-browser-sdk.pages.dev/tag-runner.html

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Collects user/device identity, browser fingerprint, page URL, referrer, and optional geolocation., Posts the collected registration payload to devices.zerogpu.ai with an operator-key header., Processes server-supplied trackingScript fields from WebSocket requests., Loads and executes arbitrary HTTPS tracking scripts in a framed runner or host document., Explicit CLI init grants \<all\_urls\> and scaffolds auto-start extension code.

- **Evidence against:** No install, preinstall, or postinstall hook is present; prepublishOnly is publisher-side., The CLI mutations occur only after an explicit zerogpu init command.
