Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. This is a customer-mounted Pluno chat SDK. The high scanner labels match documented host token-endpoint cookie use, account presentation, and page network capture for the product agent, not an install-time or covert hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-17T12:13:04.589Z - **Finished:** 2026-09-17T12:17:13.511Z - **Download time:** 777 ms - **Static scan time:** 3304 ms - **AI review time:** 244841 ms - **Total time:** 248922 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:** This is a customer-mounted Pluno chat SDK. The high scanner labels match documented host token-endpoint cookie use, account presentation, and page network capture for the product agent, not an install-time or covert hijack. - **Trigger:** A site owner installs the package and mounts the widget or calls PlunoProductAgent.init. - **Impact:** No confirmed malicious impact; expected product-agent setup and telemetry on the integrator site. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:17:13.511Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked browser SDK talking to Pluno backends - **Rationale:** Source inspection shows a first-party Pluno embed SDK with no npm install hooks and vendor-aligned app.pluno.ai traffic. The session-cookie token fetch and fetch/XHR capture are documented, user-invoked product features with redaction, not a hidden hijack. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The widget posts the page origin and URL to an integrator token endpoint with credentials include, which is the session-reuse pattern the scanner labeled as account hijack., After init, the SDK patches fetch and XMLHttpRequest and forwards capped host network events to the Pluno product-agent socket., The runtime CommonJS file is a dense minified bundle, which tripped a scanner semantic limit rather than showing a hidden installer. - **Evidence against:** package.json has no preinstall, install, or postinstall hooks; only build, check, test, and prepack., Default backend is https://app.pluno.ai and Socket.IO talks to /api/product-agent/socket.io., Network capture redacts tokens, cookies, and secrets, skips Pluno and token traffic, and can be disabled., Account data comes from optional accountLoader or initialAccount, not from stealing third-party cookies., Behavior starts only when a site mounts the widget or calls init., No self-dependency, child\_process, or reviewer-directed text. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.270. - Review the evidence and your use of @pluno/product-agent-web@0.1.270 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.
