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. A running SDK can execute JavaScript supplied through its agent transport in the embedding page. It also intercepts non-excluded host browser traffic and forwards bounded metadata and text to Pluno. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-17T12:32:38.316Z - **Finished:** 2026-09-17T12:33:55.605Z - **Download time:** 1025 ms - **Static scan time:** 3341 ms - **AI review time:** 72923 ms - **Total time:** 77289 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:** A running SDK can execute JavaScript supplied through its agent transport in the embedding page. It also intercepts non-excluded host browser traffic and forwards bounded metadata and text to Pluno. - **Trigger:** The host application initializes the SDK and the connected Pluno service sends an eligible tool event or observes browser traffic. - **Impact:** A compromised or overly privileged agent service could act in the host page and receive sensitive application data not covered by the exclusion rules. - **Evidence paths:** dist/product-agent-sdk.js, dist/product-agent-widget.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:33:55.605Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote browser-code execution and shared fetch/XHR interception. - **Rationale:** No install-time malware or covert persistence was found, but the package exposes remote host-page code execution and broad browser traffic capture. These are real dangerous capabilities requiring a warning rather than a clean verdict. - **Network endpoints:** https://app.pluno.ai, wss://app.pluno.ai/api/product-agent/embed/ws ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The SDK accepts remote execute\_code tool events and evaluates supplied JavaScript in the host page., Initialization enables network capture by default, then sends batches of intercepted host request metadata and small textual bodies over its connected socket., The capture hook replaces shared fetch and XMLHttpRequest methods, creating a broad browser-data collection surface. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The interceptor excludes Pluno, authentication, token, upload, and attachment routes, and redacts sensitive header values., The code is a browser product-agent SDK with an explicit Pluno backend default, not an install-time payload. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.272. - Review the evidence and your use of @pluno/product-agent-web@0.1.272 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.
