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. No confirmed attack surface. High scanner hits match the documented Pluno Product Agent embed: same-origin token fetch with cookies, host-network observation with redaction, and a minified runtime build. Those behaviors run only after a customer installs and mounts the widget or SDK. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-17T12:39:07.385Z - **Finished:** 2026-09-17T12:42:50.169Z - **Download time:** 255 ms - **Static scan time:** 3362 ms - **AI review time:** 219166 ms - **Total time:** 222784 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:** No confirmed attack surface. High scanner hits match the documented Pluno Product Agent embed: same-origin token fetch with cookies, host-network observation with redaction, and a minified runtime build. Those behaviors run only after a customer installs and mounts the widget or SDK. - **Trigger:** A customer installs the package and mounts the widget or imports the SDK in a browser app. - **Impact:** No unconsented install-time mutation or foreign-account hijack was shown in source. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:42:50.169Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Product-aligned Pluno embed SDK with optional host-network capture - **Rationale:** This is the published Pluno Product Agent browser SDK and widget, with no registry install hooks and only vendor-aligned endpoints. Scanner account-hijack and network findings are the documented embed path (host token endpoint, redacted fetch/XHR capture, minified runtime), not a hidden supply-chain attack. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The widget POSTs the host token endpoint with credentials include after a customer embeds it, which is the scanner account-session signal., After init the widget patches fetch and XHR and forwards capped host-request metadata as network.batch on the Pluno session socket., The CommonJS runtime is a two-line minified bundle, which tripped a scanner analysis limit rather than hiding a second payload. - **Evidence against:** package.json has no preinstall, install, or postinstall hooks; scripts are build, check, test, and prepack verify only., Capture skips Pluno, auth, token, and upload URLs, redacts secrets, and is documented host-app observation for Product Agent., Account data comes from the host-supplied loader or initial account for the Pluno chat UI, not mutation of a foreign consumer account., Auto-mount runs only when a customer includes the widget script and does not set data-pluno-auto-mount to false., No child\_process, cookie jar theft, unexpected command-and-control hosts, or runtime self-dependency chain. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.277. - Review the evidence and your use of @pluno/product-agent-web@0.1.277 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.
