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. When mounted and connected, the widget executes JavaScript delivered as a remote tool call in the host page. It also captures network events by default and sends them to the configured backend. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-17T12:35:47.534Z - **Finished:** 2026-09-17T12:36:56.085Z - **Download time:** 520 ms - **Static scan time:** 3301 ms - **AI review time:** 64729 ms - **Total time:** 68551 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:** When mounted and connected, the widget executes JavaScript delivered as a remote tool call in the host page. It also captures network events by default and sends them to the configured backend. - **Trigger:** Mounting the widget and receiving an authenticated remote tool call or network activity. - **Impact:** A compromised or over-privileged backend can run page-context code and receive browser activity metadata. - **Evidence paths:** dist/product-agent-widget.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:36:56.085Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote JavaScript evaluation and socket-based network-event reporting. - **Rationale:** This is a dangerous remote agent capability in a browser bundle, not confirmed malware. Its default network capture expands the exposure, so it should be warned rather than published as clean. - **Files touched:** dist/product-agent-widget.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The widget accepts remote execute-code tool calls containing arbitrary JavaScript., It creates and invokes an asynchronous function from that JavaScript in the embedding page., Network capture is enabled by default and sends captured page events through its socket. - **Evidence against:** The manifest has no install lifecycle hook., The backend URL is supplied by the integrator rather than hard-coded., The bundle includes redaction for named secret fields and common token formats. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.273. - Review the evidence and your use of @pluno/product-agent-web@0.1.273 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.
