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. The browser runtime can execute a remote tracking script supplied through a task field. No destination restriction is visible in the inspected path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-25T21:00:25.335Z - **Finished:** 2026-09-25T21:01:23.312Z - **Download time:** 1013 ms - **Static scan time:** 1302 ms - **AI review time:** 55661 ms - **Total time:** 57977 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 browser runtime can execute a remote tracking script supplied through a task field. No destination restriction is visible in the inspected path. - **Trigger:** A task containing trackingScript reaches runtime task handling. - **Impact:** A controlling task source could run arbitrary JavaScript in the embedding document context. - **Evidence paths:** dist/zerogpu-browser-sdk.esm.js - **Review source:** ai\_review - **Reviewed:** 2026-09-25T21:01:23.312Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The supplied URL is assigned to a dynamically appended script element. - **Rationale:** The unrestricted dynamic script-loading path is a dangerous remote-code-execution capability. Static inspection does not establish a specific active payload or malicious intent, so a warning is appropriate rather than a block. ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The runtime loads a script element from a supplied URL., Task handling passes trackingScript into that script-loading path without an allowlist shown., The package metadata has build and publish scripts but no automatic install lifecycle hook. - **Evidence against:** No install-time execution was identified. ## Affected versions and remediation This report applies to @zerogpu/browser-extension-sdk@0.3.1. - Review the evidence and your use of @zerogpu/browser-extension-sdk@0.3.1 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.
