## Verdict summary
**Blocked & quarantined** — A service-controlled external script can execute with the embedding page's privileges and may access page data or make authenticated same-origin requests.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 0.4.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The browser entrypoint accepts a runtime trackingScript URL from a task and loads it as executable JavaScript in the host page. The URL is only constrained to HTTPS, not to an approved host.

## Security analysis

### Published attack-surface review

- **Summary:** The browser entrypoint accepts a runtime trackingScript URL from a task and loads it as executable JavaScript in the host page. The URL is only constrained to HTTPS, not to an approved host.

- **Trigger:** A browser client receives a task containing trackingScript.

- **Impact:** A service-controlled external script can execute with the embedding page's privileges and may access page data or make authenticated same-origin requests.

- **Evidence paths:** dist/zerogpu-browser-sdk.esm.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-26T06:01:03.854Z

### AI review details

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

- **Mechanism:** The bundle appends a script element using the supplied URL; its fallback issues a credential-including fetch to that URL.

- **Attack narrative:** After the SDK is imported and connected to its orchestrator, a task can provide trackingScript. The bundle treats that value as an HTTPS script URL and appends it to the document, allowing the remote response to execute in the host page. Its fallback also contacts the supplied URL with browser credentials included. This is a live remote-code execution path controlled through service task data, not a local model-loading requirement.

- **Rationale:** The browser bundle contains an active, unrestricted remote script-loading path driven by task data. This creates a concrete remote-code execution surface in applications that use the SDK.

- **Network endpoints:** https://devices.zerogpu.ai

### Review decision

- **Verdict:** Malicious

- **Confidence:** 92.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The manifest exposes the browser SDK bundle as the package import entrypoint., The bundle processes a task trackingScript value through its tracking handler., That handler creates and appends a script element whose HTTPS URL is supplied at runtime., If script loading is unavailable, the handler fetches the supplied URL with included browser credentials., The bundle is configured to connect to the ZeroGPU orchestrator at https://devices.zerogpu.ai.

- **Evidence against:** The manifest contains no npm preinstall, install, or postinstall lifecycle hook., The remote script path requires a received task carrying a trackingScript value.

## Affected versions and remediation

This report applies to @zerogpu/browser-extension-sdk@0.4.0.

- Avoid installing @zerogpu/browser-extension-sdk@0.4.0. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
