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 supply-chain attack. Install does nothing, and runtime network hooks, account APIs, and browser code execution belong to the embedded Product Agent after the host mounts it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-17T12:39:06.389Z - **Finished:** 2026-09-17T12:47:15.002Z - **Download time:** 756 ms - **Static scan time:** 3856 ms - **AI review time:** 484001 ms - **Total time:** 488613 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 supply-chain attack. Install does nothing, and runtime network hooks, account APIs, and browser code execution belong to the embedded Product Agent after the host mounts it. - **Trigger:** A host app installs the package and calls PlunoProductAgent.init or loads the widget script. - **Impact:** No unconsented install-time or hidden third-party impact was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:47:15.002Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked Pluno product-agent embed SDK - **Rationale:** This is a first-party Pluno embed SDK with no install-time execution. Scanner labels for session hijack and limited semantic analysis match documented, user-invoked product-agent capture and a minified runtime helper, not a hidden attack. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The published manifest has no preinstall, install, or postinstall scripts; remaining scripts are build, check, test, and prepack verify., After SDK init the widget patches window.fetch and XMLHttpRequest and can send network.batch events on the Pluno session socket., Browser tool calls compile session javascript with an async Function constructor used as execute\_code., dist/product-agent-runtime.cjs is a one-line minified CommonJS runtime, which is why automated semantic analysis stopped early. - **Evidence against:** This is a documented Pluno Product Agent browser SDK; capture and tool execution start only after explicit init or script-tag widget mount., Network capture skips auth, token, upload, and pluno.ai URLs, redacts secrets, and restores fetch and XHR when the last instance is destroyed., Account and preference code is Pluno product-agent state in namespaced localStorage, not host-account takeover., twitter.com, instagram.com, and linkedin.com are share links; fonts.gstatic.com is a font file; socket.io is the bundled client., No third-party exfil host, install-time mutation, or lifecycle self-dependency is present. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.275. - Review the evidence and your use of @pluno/product-agent-web@0.1.275 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.
