This is a vendor browser SDK for embedding the Pluno product agent. npm install does not run package code; fetch wrapping, account reads, and helper JavaScript run only after the host mounts the widget and talks to Pluno. - **Trigger:** A host app installs the package and calls init or mounts the widget; registry install does not execute this package. - **Impact:** No unconsented install-time mutation or covert third-party exfil chain beyond the intended embedded-agent product. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T14:41:17.397Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** No confirmed malicious attack surface - **Rationale:** High scanner labels are noisy: host network capture, account projection, and helper JavaScript are the documented Pluno product-agent client, not a hidden hijack. There are no install hooks, no foreign agent-control writes, and endpoints stay on the Pluno product. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** After the host mounts the widget, it wraps fetch and XMLHttpRequest and forwards capped host request metadata to the Pluno websocket as network.batch., On websocket auth.ok the widget stores server-provided helper JavaScript and can run it with an async Function constructor., Account reads use the integrator accountLoader or initialAccount plus Pluno user fields, which the scanner labeled as session hijack., package.json has no preinstall, install, or postinstall hooks; scripts are build, check, test, and prepack verify only., dist/product-agent-runtime.cjs is a minified product runtime; the scanner stopped semantic analysis on this file without showing a second payload. - **Evidence against:** This is a documented Pluno browser SDK and chat widget, not an install-time dropper., Network targets are vendor-aligned: app.pluno.ai, pluno.ai, fonts.gstatic.com, and social share links., Captured request bodies skip token, Pluno, streaming, and large payloads and run a redaction pipeline before send., JavaScript helper execution and account APIs run only after the host mounts the agent and authenticates to Pluno., No child\_process, env harvesting, self-dependency lifecycle chain, or reviewer-directed social engineering. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.281. - Review the evidence and your use of @pluno/product-agent-web@0.1.281 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.
