Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface was established. The package provides authenticated embedded buyer-agent pages with fixed destination origins and origin checks. - **Trigger:** An authorized user opens a buyer-agent or order-entry page. - **Impact:** The fixed iframe services receive the user token needed for the agent functionality; no unrestricted credential export or install-time execution was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-19T14:22:06.639Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Restricted cross-origin postMessage authentication handoff to embedded iframe applications. - **Rationale:** The flagged credential handling is a visible, route-gated authentication handoff to hard-coded iframe origins, with both target-origin and sender-window checks. Inspection found no install hook abuse, self-dependency chain, hidden execution, or unrestricted exfiltration sink. - **Network endpoints:** buyer-bulk-ops-agent.vercel.app, order-entry-agent.vercel.app ### Review decision - **Verdict:** Clean - **Confidence:** 82.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The manifest has no preinstall, install, or postinstall hook; its only lifecycle-related script is a Husky prepare command., The buyer-agent iframe destination is a fixed development or production URL, not an operator-configured endpoint., Authentication data is sent only to the computed fixed iframe origin, and incoming messages must match both that origin and the embedded iframe window., The token forwarding occurs only when an authorized user visits the dedicated buyer-agent page. - **Evidence against:** The package forwards an existing VTEX authentication token to external iframe applications, so those fixed services must be trusted., The manifest declares a prepare script, but the inspected source shows no broad project mutation or automatic payload chain. ## Affected versions and remediation This report applies to @vtex/faststore-plugin-buyer-portal@2.0.26. - Review the evidence and your use of @vtex/faststore-plugin-buyer-portal@2.0.26 before allowing it.
