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 widget automatically instruments fetch and XMLHttpRequest, collecting metadata and selected request or response content from non-excluded URLs. It batches those events to its configured product-agent socket. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-22T00:43:48.870Z - **Finished:** 2026-09-22T00:45:16.825Z - **Download time:** 756 ms - **Static scan time:** 3701 ms - **AI review time:** 83497 ms - **Total time:** 87955 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 widget automatically instruments fetch and XMLHttpRequest, collecting metadata and selected request or response content from non-excluded URLs. It batches those events to its configured product-agent socket. - **Trigger:** Widget initialization with network capture not disabled. - **Impact:** Requests to third-party application endpoints may have bounded, redacted metadata or body content forwarded to the configured agent backend. No install-time attack or hidden fixed exfiltration endpoint was identified. - **Evidence paths:** dist/product-agent-widget.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T00:45:16.825Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The widget replaces browser network APIs, applies URL and content filters, queues captured events, then emits a network.batch socket message. - **Rationale:** No malicious install hook, persistence, or hidden payload was found. However, automatic interception and forwarding of browser network events is a meaningful data-exposure capability despite the implemented filters. - **Network endpoints:** https://app.pluno.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package has no npm install lifecycle hook; its only lifecycle-like script is prepack., The widget enables network capture automatically unless the caller sets disableNetworkCapture., Network capture replaces browser fetch and XMLHttpRequest methods and records request metadata and bodies., Captured events are sent as network.batch over the connected socket., The capture filter excludes several authentication, token, upload, and Pluno URLs, and redacts sensitive header values., The CommonJS runtime entry is a local compiled module with named exports. - **Evidence against:** The captured destination is the configured backend, with a built-in default of https://app.pluno.ai rather than a hidden unrelated host., The inspected capture code includes bounded collection and redaction controls. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.286. - Review the evidence and your use of @pluno/product-agent-web@0.1.286 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.
