Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. At runtime, an orchestrator task can supply an HTTPS tracking script that the SDK injects into the host document. The SDK also sends device profiling data to its orchestrator. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-04T17:00:50.501Z - **Finished:** 2026-09-04T17:03:03.634Z - **Download time:** 1521 ms - **Static scan time:** 3346 ms - **AI review time:** 128265 ms - **Total time:** 133133 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:** At runtime, an orchestrator task can supply an HTTPS tracking script that the SDK injects into the host document. The SDK also sends device profiling data to its orchestrator. - **Trigger:** A configured SDK connects to the orchestrator and receives a task containing trackingScript. - **Impact:** The remote task source can run arbitrary HTTPS-hosted JavaScript in the host page context and receive detailed device metadata. - **Evidence paths:** dist/extension/zerogpu-offscreen.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T17:03:03.634Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote script injection and device-profile reporting. - **Rationale:** The package has no automatic install hook, but its runtime accepts a remotely supplied script URL and executes it in the host document. That concrete remote execution path warrants a warning. - **Files touched:** dist/extension/zerogpu-offscreen.js - **Network endpoints:** devices.zerogpu.ai, cdn.jsdelivr.net ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** A server-supplied trackingScript is executed by adding it as a script in the host document., The SDK collects a detailed device profile and posts it to its orchestrator., The extension runtime dynamically imports executable code from a CDN. - **Evidence against:** package.json has no install, preinstall, or postinstall hook., The manifest-changing CLI runs only for explicit vendor or init commands., The package has no self-dependency or child-process execution at runtime. ## Affected versions and remediation This report applies to @zerogpu/browser-extension-sdk@0.2.4. - Review the evidence and your use of @zerogpu/browser-extension-sdk@0.2.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
