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 package is a documented Pluno Product Agent browser SDK. Fetch and XHR capture, account loaders, and token refresh run only after a host app mounts the SDK or widget and talk to Pluno or the host token endpoint. Scanner labels for session hijack and limited semantic analysis come from that product surface and a minified runtime bundle, not from a hidden attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-17T12:13:04.347Z - **Finished:** 2026-09-17T12:16:06.815Z - **Download time:** 505 ms - **Static scan time:** 3821 ms - **AI review time:** 178141 ms - **Total time:** 182468 ms The recorded confidence comes from the underlying analysis.

Fetch and XHR capture, account loaders, and token refresh run only after a host app mounts the SDK or widget and talk to Pluno or the host token endpoint. Scanner labels for session hijack and limited semantic analysis come from that product surface and a minified runtime bundle, not from a hidden attack. - **Trigger:** A consumer installs the package and later imports the SDK or mounts the widget in a browser. - **Impact:** No install-time mutation, secret theft, or unconsented foreign control-surface write was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:16:06.815Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Product-aligned embed SDK with optional host network capture - **Rationale:** The package is a published Pluno Product Agent browser SDK with no registry install hooks. Fetch and XHR capture, account loaders, and token refresh are documented embed features aimed at app.pluno.ai and the host token endpoint, not an install-time hijack. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The widget installs shared window.fetch and XMLHttpRequest hooks that record host request metadata., The default token helper POSTs the page origin and URL with credentials include., The CJS runtime is a dense minified one-liner, which limited automated semantic analysis., The published manifest is a browser SDK with build/check/test/prepack scripts and no install hook. - **Evidence against:** There is no preinstall, install, or postinstall script; prepack only verifies package contents for publishing., Default backend is https://app.pluno.ai; other URLs are Pluno pages, Google fonts, and social share links., Network capture skips token and Pluno bodies, redacts secrets, and removes hooks when the last instance is destroyed., Account APIs load Pluno workspace, credits, and host-supplied presentation, not takeover of the embedding site account., No child\_process, eval payload, cookie theft, or foreign AI-agent config writes were found., Behavior runs only after a consumer imports the SDK or mounts the widget. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.271. - Review the evidence and your use of @pluno/product-agent-web@0.1.271 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.
