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. When initialized, the SDK monitors host-page network activity and sends redacted batches to Pluno. An authenticated Pluno server can also direct it to run JavaScript in the current embedding page. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-17T12:58:43.537Z - **Finished:** 2026-09-17T13:00:18.535Z - **Download time:** 254 ms - **Static scan time:** 3689 ms - **AI review time:** 91055 ms - **Total time:** 94998 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:** When initialized, the SDK monitors host-page network activity and sends redacted batches to Pluno. An authenticated Pluno server can also direct it to run JavaScript in the current embedding page. - **Trigger:** Import and initialize the SDK or mount the widget, then establish its authenticated socket connection. - **Impact:** Host request metadata and limited textual content may leave the page; a compromised or overly trusted backend could execute code with the page's origin privileges. - **Evidence paths:** dist/product-agent-sdk.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T13:00:18.535Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default network interception plus server-directed browser JavaScript execution. - **Rationale:** The package has real data-collection and remote browser-code capabilities, so it warrants a warning. Static source does not establish malicious install behavior or a covert attack campaign. - **Network endpoints:** app.pluno.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** SDK initialization enables network capture by default., The capture layer replaces fetch and XHR methods and records request metadata and textual bodies., Captured events are batched and sent over the authenticated Pluno socket., Server-delivered tool calls can execute supplied JavaScript in the embedding page. - **Evidence against:** No npm install lifecycle hook or self-dependency is present., Captured values undergo token and secret redaction before batching., The network and browser-agent behavior is consistent with the package's embedded product-agent role. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.279. - Review the evidence and your use of @pluno/product-agent-web@0.1.279 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.
