## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 2.0.37
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection confirms automatic cross-origin forwarding of VTEX tokens and customer/session data to fixed external hosts. Because the hosts are integrated agent applications but their trust and consent boundaries are unresolved, this warrants a warning rather than a malicious verdict.

## Latest scan

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:** The authenticated agent pages send VTEX authentication tokens and customer data to fixed external iframe origins. The transfer is confirmed, but the inspected source does not establish whether those recipients are trusted, so the credential exposure risk remains unresolved.

- **Trigger:** An authorized user loads either agent page and its iframe signals readiness or finishes loading.

- **Impact:** The external application receives session credentials that could enable access to the associated VTEX account, along with customer identifiers.

- **Evidence paths:** src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx, src/pages/buyer-organization-manager.tsx, src/features/order-entry/layouts/OrderEntryLayout.tsx, src/pages/order-entry.tsx

- **Review source:** ai\_review

- **Reviewed:** 2026-10-15T13:34:59.001Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The page sends authentication and account data through postMessage to the origin selected by a hardcoded external URL.

- **Rationale:** Source inspection confirms automatic cross-origin forwarding of VTEX tokens and customer/session data to fixed external hosts. Because the hosts are integrated agent applications but their trust and consent boundaries are unresolved, this warrants a warning rather than a malicious verdict.

- **Files touched:** src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx, src/pages/buyer-organization-manager.tsx, src/features/order-entry/layouts/OrderEntryLayout.tsx, src/pages/order-entry.tsx

- **Network endpoints:** https://buyer-bulk-ops-agent.vercel.app/app/buyer-bulk-ops-agent, https://order-entry-agent.vercel.app/app/order-entry-agent

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Authenticated portal pages obtain a VTEX token from session context or cookies and pass it into the agent layouts., The buyer organization manager layout sends the token and customer identifiers to a fixed external iframe origin when the iframe signals readiness or loads., The order-entry layout sends VTEX tokens, session data, and customer identifiers to a second fixed external iframe origin., The recipients are named for the embedded agent features, but the source does not establish that either external host is a trusted credential recipient or show recipient-specific consent.

- **Evidence against:** The pages are authenticated and the external frames correspond to the package’s buyer-agent and order-entry features; this suggests a product integration, but does not resolve the credential exposure risk.
