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 SDK executes a remotely supplied tracking script in the host page or WebView. This gives the service supplying that URL code execution in the host document context. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-25T20:50:22.237Z - **Finished:** 2026-09-25T20:51:59.824Z - **Download time:** 1023 ms - **Static scan time:** 2659 ms - **AI review time:** 93904 ms - **Total time:** 97587 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The SDK executes a remotely supplied tracking script in the host page or WebView. This gives the service supplying that URL code execution in the host document context. - **Trigger:** A started SDK lifecycle receives a request containing a trackingScript value. - **Impact:** Remote code can access the host page's DOM and same-origin browser data available to that page. - **Evidence paths:** dist/zerogpu-browser-sdk.esm.js - **Review source:** ai\_review - **Reviewed:** 2026-09-25T20:51:59.824Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The request dispatches to the tracking handler, which loads the supplied HTTPS URL as a script in the document. - **Attack narrative:** After initialization, the SDK connects to its orchestrator and processes served requests. A request can contain a trackingScript URL. The package passes that URL to a handler that appends it as a script to the host document, causing remote code to run in the page or WebView context. The URL is not restricted to a fixed trusted host; only its HTTPS scheme is checked. - **Rationale:** The package contains an active remote-script execution path driven by a service request, not merely a configurable API client or inert payload. The lack of an install hook does not remove the runtime host-context code-execution risk. - **Network endpoints:** https://devices.zerogpu.ai ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The SDK accepts a tracking-script value from a served request and invokes its tracking-script handler., The handler creates a script element, assigns the supplied URL, and appends it to the host document., The tracking handler is designed to execute supplied scripts in a normal page or WebView., Initialization starts the lifecycle using a baked-in ZeroGPU orchestrator endpoint. - **Evidence against:** The manifest contains no npm install lifecycle hook., The bundled Transformers helper restricts its environment token header to Hugging Face hosts. ## Affected versions and remediation This report applies to @zerogpu/browser-extension-sdk@0.3.0. - Avoid installing @zerogpu/browser-extension-sdk@0.3.0. 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. ## Public findings ### 1.
