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 SDK monitors browser traffic and accepts remote browser-tool calls. A received code tool call can execute JavaScript in the embedding page and return its output. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-17T12:35:46.732Z - **Finished:** 2026-09-17T12:37:12.470Z - **Download time:** 1271 ms - **Static scan time:** 3351 ms - **AI review time:** 81114 ms - **Total time:** 85738 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 SDK monitors browser traffic and accepts remote browser-tool calls. A received code tool call can execute JavaScript in the embedding page and return its output. - **Trigger:** A web application initializes the SDK and its connected backend delivers an execute\_code tool call. - **Impact:** A trusted or compromised backend could run page-context actions and access data available to that page. - **Evidence paths:** dist/product-agent-sdk.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:37:12.470Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote browser JavaScript execution plus intercepted network-event reporting. - **Rationale:** The package contains a real remote code-execution capability in customer browser pages and default network monitoring, which warrants a warning. Static inspection found no install hook or concrete malicious behavior, so blocking is not supported. - **Network endpoints:** https://app.pluno.ai, /api/product-agent/socket.io ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The SDK accepts execute\_code tool calls and runs supplied JavaScript with AsyncFunction in the host page., Initialization enables fetch/XHR traffic capture by default and sends captured batches over its connected transport., The SDK connects to a Pluno Socket.IO endpoint, creating a remote command path to the browser. - **Evidence against:** package.json has no install lifecycle hook or self-dependency., The traffic collector excludes Pluno, auth, token, upload, and signed-URL requests., The only fixed backend host is app.pluno.ai, consistent with the package identity. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.269. - Review the evidence and your use of @pluno/product-agent-web@0.1.269 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.
