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 widget automatically instruments fetch and XMLHttpRequest, then sends captured request metadata and bodies to its connected backend. It also executes JavaScript supplied in server tool calls in the embedding page. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-22T14:02:55.102Z - **Finished:** 2026-09-22T14:12:37.332Z - **Download time:** 759 ms - **Static scan time:** 3742 ms - **AI review time:** 577728 ms - **Total time:** 582230 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 widget automatically instruments fetch and XMLHttpRequest, then sends captured request metadata and bodies to its connected backend. It also executes JavaScript supplied in server tool calls in the embedding page. - **Trigger:** Mounting and connecting the widget enables capture; receipt of an execute\_code tool call activates code execution. - **Impact:** A compromised or overly trusted service backend can inspect eligible page network traffic and run arbitrary page-context JavaScript. - **Evidence paths:** dist/product-agent-widget.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T14:12:37.332Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The widget replaces browser request APIs, batches nonexcluded events over its socket, and constructs an async function from server-provided JavaScript. - **Rationale:** The package has no install hook, but its widget enables traffic capture by default and executes server-supplied JavaScript in the host page. These are dangerous capabilities with no local consent gate beyond embedding and backend trust. - **Network endpoints:** https://app.pluno.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package exports a browser widget entrypoint., Widget initialization enables network capture by default unless the caller disables it., Captured nonexcluded browser requests are queued and sent as network batches., A connected server can issue an execute\_code tool call whose JavaScript is compiled and run in the page. - **Evidence against:** The capture filter excludes Pluno, authentication, token, upload, and signed-URL requests, and redacts several credential-like fields., No npm install lifecycle hook is declared. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.288. - Review the evidence and your use of @pluno/product-agent-web@0.1.288 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.
