## Verdict summary
**Blocked & quarantined** — A server-selected HTTPS script can run in a host page context; tracking endpoints can receive browser cookies and identifying device and page data.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 0.2.3
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

After explicit integration, the SDK sends a detailed device and browsing profile to its orchestrator. It accepts server-directed tracking URLs, executes HTTPS scripts in applicable host pages, and otherwise sends credentialed tracking requests.

## Security analysis

### Published attack-surface review

- **Summary:** After explicit integration, the SDK sends a detailed device and browsing profile to its orchestrator. It accepts server-directed tracking URLs, executes HTTPS scripts in applicable host pages, and otherwise sends credentialed tracking requests.

- **Trigger:** A consumer runs the CLI to integrate the extension, then the extension starts the SDK and receives a task containing trackingScript or trackingPixel.

- **Impact:** A server-selected HTTPS script can run in a host page context; tracking endpoints can receive browser cookies and identifying device and page data.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-31T22:56:51.832Z

### AI review details

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

- **Mechanism:** Remote tracking-script execution and credentialed beacon delivery.

- **Attack narrative:** The explicit init command broadens a consumer extension's permissions and starts the SDK on extension startup. The SDK profiles the device and page before registering with the vendor service. Runtime task data can contain a trackingScript, which is passed to a script element and runs in an applicable host document; if that path fails, a tracking request is sent with included credentials. This gives the remote service a practical route to execute server-selected web code and to cause cookie-bearing requests outside the stated inference function.

- **Rationale:** This is concrete remote script execution and browser-data exposure, not merely a bundled model runtime. The lack of an automatic npm install hook reduces installation risk but does not neutralize the runtime behavior.

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

- **Network endpoints:** devices.zerogpu.ai, zerogpu-browser-sdk.pages.dev

### Review decision

- **Verdict:** Malicious

- **Confidence:** 94.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Its CLI modifies a consumer extension manifest to add broad host access and extension wiring., The runtime collects identifiers, Telegram profile fields, hardware details, page URL, and referrer, then posts the profile to the orchestrator., Server WebSocket messages can supply tracking scripts that are executed through a script element in the host document context., The fallback tracking request deliberately includes browser cookies.

- **Evidence against:** package.json has no automatic install lifecycle hook., The consumer-project changes require an explicit CLI command.
