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 the widget globally observes browser network activity and forwards batches to the Pluno backend. This can disclose bounded metadata and textual request or response content from unrelated application requests. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-09-17T12:32:37.938Z - **Finished:** 2026-09-17T12:34:01.711Z - **Download time:** 757 ms - **Static scan time:** 3985 ms - **AI review time:** 79029 ms - **Total time:** 83773 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 the widget globally observes browser network activity and forwards batches to the Pluno backend. This can disclose bounded metadata and textual request or response content from unrelated application requests. - **Trigger:** Initializing the SDK or widget without disableNetworkCapture. - **Impact:** Potential disclosure of application request metadata and textual content to the service backend. - **Evidence paths:** dist/product-agent-widget.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:34:01.711Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global fetch and XMLHttpRequest interception followed by socket event delivery. - **Rationale:** The package has no install-time attack chain, but its default global interception and external transmission of host application traffic is a concrete data-exposure capability. The filtering reduces risk but does not establish that non-excluded captured data is safe to export. - **Network endpoints:** https://app.pluno.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The widget enables network capture during initialization unless the caller explicitly disables it., It wraps browser fetch calls and collects request URLs, methods, headers, and textual request bodies., Captured events are batched and sent to the backend over the authenticated socket., The exclusion list omits some sensitive routes but still permits collection from other application requests. - **Evidence against:** The manifest has no install lifecycle hook or self-dependency., The collector excludes Pluno, authentication, token, upload, and binary requests, and caps captured text. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.263. - Review the evidence and your use of @pluno/product-agent-web@0.1.263 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.
